Check Digit Verification of cas no
The CAS Registry Mumber 233587-74-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,3,3,5,8 and 7 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 233587-74:
(8*2)+(7*3)+(6*3)+(5*5)+(4*8)+(3*7)+(2*7)+(1*4)=151
151 % 10 = 1
So 233587-74-1 is a valid CAS Registry Number.

, p. 1083 - 1092 (2001)
A stereoselective synthesis of both isomers of the pharmaceutically important morphine 6-β-D-glucuronide (M6G) and its analogs was developed. The method is based on the use of ZnBr2 for the key coupling reaction. It was shown that the α/β stere
