Check Digit Verification of cas no
The CAS Registry Mumber 161804-41-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,1,8,0 and 4 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 161804-41:
(8*1)+(7*6)+(6*1)+(5*8)+(4*0)+(3*4)+(2*4)+(1*1)=117
117 % 10 = 7
So 161804-41-7 is a valid CAS Registry Number.

Stereoselective synthesis of a new kind of natural glyco-cyclophane
Wang, Yulan,Mao, Jianmin,Cai, Mengshen
, p. 2093 - 2097 (1999)
A new kind of natural glyco-cyclophane, clemochinenoside-A (1), has been stereoselectively synthesized from 1,6-di-O-acetyl-2,3,4-tri-O-benzyl- Dglucopyranose. 4-Dimethylaminopyridine and dicyclohexylcarbodiimide were first used to catalyze the glyco-cycl
