Check Digit Verification of cas no

The CAS Registry Mumber 213208-15-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,3,2,0 and 8 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 213208-15:
(8*2)+(7*1)+(6*3)+(5*2)+(4*0)+(3*8)+(2*1)+(1*5)=82
82 % 10 = 2
So 213208-15-2 is a valid CAS Registry Number.

Synthesis of some substituted dibenzodiazepinones and pyridobenzodiazepinones

Cohen, Victor I.,Jin, Biyun,Cohen, Emil I.,Zeeberg, Barry R.,Reba, Richard C.

, p. 675 - 686 (1998)

Some fluoro- and iodo-derivative of 5-[[4-[(4-diisobutylamino)butyl]-1- phenyl]acetyl]-10,11-dihydro-5H-dibenzo[b,e][1,4]diazepin-11-one and 11-[[4- [(dialkylamino)butyl]-1-phenyl]acetyl]-5,11-dihydro-6H-pyrido[2,3- b][1,4]benzodiazepin-6-ones 6 (Scheme 1) and their analogues were synthesized. The synthesis of dibenzodiazepinones 1 (Scheme 1) is based on the reaction between 1,4-phenylenediamine and substituted benzoic acids. The intermediate pyridobenzodiazepinones 3 (Scheme 1) were prepared by condensation of 2-chloro-3-aminopyridine with methyl anthranilate and its chlorine derivative. The condensation of 4-[(halo)alkyl]phenylacetyl chloride with dibenzodiazepinones and pyridobenzodiazepinones followed by the reaction of mono- or dialkyl- or dialkenylamine provides 6 (Scheme 1).
