Check Digit Verification of cas no

The CAS Registry Mumber 38491-55-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,8,4,9 and 1 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 38491-55:
(7*3)+(6*8)+(5*4)+(4*9)+(3*1)+(2*5)+(1*5)=143
143 % 10 = 3
So 38491-55-3 is a valid CAS Registry Number.

DBU-promoted condensation of acyldiazomethanes to aldehydes and imines under catalytic conditions

Jiang, Nan,Wang, Jianbo

, p. 1285 - 1287 (2002)

The condensation of acyldiazomethanes to aldehydes and imines can be promoted with catalytic amount of DBU. The condensation gives β-hydroxy α-diazo carbonyl compounds or β-amino α-diazo carbonyl compounds in high yields.
