Check Digit Verification of cas no

The CAS Registry Mumber 137129-45-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,1,2 and 9 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 137129-45:
(8*1)+(7*3)+(6*7)+(5*1)+(4*2)+(3*9)+(2*4)+(1*5)=124
124 % 10 = 4
So 137129-45-4 is a valid CAS Registry Number.

New facile preparation of dihydro spiro-1,5-benzodiazepines

Shanthan Rao,Venkataratnam

, p. 1811 - 1817 (2007/10/02)

2,3-Cycloalkano-3,4-dihydro(5H)-7-benzoyl-1,5-benzodiazepine-4- spirocycloalkanes have been prepared from 4-benzoyl-o-phenylenediamine and cycloalkanones in presence of acetic acid. Only in the case of cyclohexanones, dihydrospiro benzimidazoles are formed as coproducts which are absent in others.
