Check Digit Verification of cas no

The CAS Registry Mumber 129195-09-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,1,9 and 5 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 129195-09:
(8*1)+(7*2)+(6*9)+(5*1)+(4*9)+(3*5)+(2*0)+(1*9)=141
141 % 10 = 1
So 129195-09-1 is a valid CAS Registry Number.

In connection with our work on styryl derivatives of benzodiazinones, we have prepared the 7-N, N-dimethylamino-3-methyl-l , 4-benzodiazin-2-one 4a and two chromo-and fluoroionophores derived from the monoaza-15-crown-5 and styrylbenzodiazinones. A structural study of these compounds by 1H and l3C NMR, UV spectrophotometry, and molecular modelling was carried out. Unlike styrylbenzoxazinones, styrylbenzodiazinone derivatives showed a Z/E isomerization in acetonitrile solution. The isomerization was photoinduced, was catalysed by metallic ions, and was a reversible process. As well, an efficient alkylation reaction of the lactam function of benzodiazinones is described.

A colorant for coloring keratin fibers wherein the colorant contains a substantive dye which is a 4-nitroaniline derivative corresponding to formula (I): 1in which R1, R2, R3 and R4 independently of one another represent a hydrogen atom, an alkyl, hydroxyalkyl, alkoxyalkyl, carbamyl alkyl, mesylaminoalkyl, acetylaminoalkyl, ureidoalkyl, carbalkoxyaminoalkyl, sulfalkyl, piperidinoalkyl, morpholinoalkyl or phenyl radical optionally substituted by an amino group in the para position, the alkyl or alkoxy groups containing 1 to 4 carbon atoms, with the proviso that the four substituents R1, R2, R3 and R4 do not simultaneously represent hydrogen, and the groups —NR1R2 and —NR3R4 may also represent an aziridine, acetidine, pyrrolidine, piperidine, azepan, azocine, morpholine, thiomorpholine or piperazine ring which may also bear another substituent R8 at the nitrogen atom, R8 being a hydrogen atom, a (C1-4)-alkyl, hydroxy-(C2-3)-alkyl, (C1-4)-alkoxy-(C2-3)-alkyl, amino-(C2-3)-alkyl or 2,3-dihydroxypropyl group, and R5, R6 and R7 independently of one another represent ahydrogen atom, a halogen atom, a (C1-4)-alkyl, (C1-4)-alkoxy, carboxy, sulfo or (C2-4)-hydroxyalkyl group, or a physiologically compatible salt of the compounds with an inorganic or organic acid.
