Check Digit Verification of cas no

The CAS Registry Mumber 4222-96-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,2 and 2 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 4222-96:
(6*4)+(5*2)+(4*2)+(3*2)+(2*9)+(1*6)=72
72 % 10 = 2
So 4222-96-2 is a valid CAS Registry Number.

SILICA GEL PROMOTED SELECTIVE HYDROLYSIS OF 3-METHOXY-2,5(10)-DIENE STEROIDS

Lui, Li-Gong,Zhang, Tong,Li, Zhen-Su

, p. 2999 - 3006 (2007/10/03)

Hydrolysis of 3-methoxy-2,5(10)-diene steroids (1a-c) via oxalic acid in the presence of silica gel was developed as a fast selective synthesis method toward corresponding 5(10)-en-3-ones (2a-c) in good yield (51-94percent).This also provided a new method for selective ketalisation of 17-keto over 3-keto (2c).
