Check Digit Verification of cas no

The CAS Registry Mumber 138995-69-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,9,9 and 5 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 138995-69:
(8*1)+(7*3)+(6*8)+(5*9)+(4*9)+(3*5)+(2*6)+(1*9)=194
194 % 10 = 4
So 138995-69-4 is a valid CAS Registry Number.

A mild, efficient methodology for the synthesis of carbacephem intermediates via phase transfer catalysis

Doecke,Staszak,Luke

, p. 985 - 988 (1991)

A high yielding, one-pot method for the transesterification of β-lactam intermediates is presented. The methodology involves the dual use of a phase transfer catalyst to carry out both a hydrolysis and re-esterification.
