Check Digit Verification of cas no

The CAS Registry Mumber 135386-76-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,3,8 and 6 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 135386-76:
(8*1)+(7*3)+(6*5)+(5*3)+(4*8)+(3*6)+(2*7)+(1*6)=144
144 % 10 = 4
So 135386-76-4 is a valid CAS Registry Number.

An efficient method for hydrolysis of N-monosubstituted amides utilization of intramolecular N---O acyl migration in hydroxypivalimides

Tsunoda, Tetsuto,Sasaki, Osamu,Takeuchi, Osamu,Ito, Sho

, p. 3925 - 3934 (2007/10/02)

An efficient and versatile method for the hydrolysis of N-monosubstituted carboxamides has been developed. The method consists of two steps: the conversion to acetoxypivalimides (≥90% yield) and their mild alkaline hydrolysis (70 90% yield). No epimerization at the α-position of the acyl group took place in the process. The amine part of the original amides can be recovered in good yield.
