187405-74-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 187405-74-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,7,4,0 and 5 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 187405-74:
(8*1)+(7*8)+(6*7)+(5*4)+(4*0)+(3*5)+(2*7)+(1*4)=159
159 % 10 = 9
So 187405-74-9 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 (2007/10/03)
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
