Check Digit Verification of cas no

The CAS Registry Mumber 14204-96-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,2,0 and 4 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 14204-96:
(7*1)+(6*4)+(5*2)+(4*0)+(3*4)+(2*9)+(1*6)=77
77 % 10 = 7
So 14204-96-7 is a valid CAS Registry Number.

ETUDE EXPERIMENTALE ET THEORIQUE DE LA PHOTOLYSE DE DERIVES DU CYCLE PYRAZOLONE

Cardy, H.,Poquet, E.

, p. 2279 - 2286 (2007/10/02)

When irradiated in protic solvents such as water and primary alcohols, pyrazolinone derivatives undergo photocleavage between the two nitrogen atoms.Substituting the C-4 atom with an electronegative group stabilizes the open chain which is obtained but a thermal transposition takes place from the linear intermediate when C-4 carries a hydrogen atom or a methyl group.The STO/3G ab initio scheme was used to study the photocleavage and the influence of the C-4 substituent, giving evidence of a mechanism which involves triplet excited states of the ?, ?* type.
