Check Digit Verification of cas no

The CAS Registry Mumber 1374991-22-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,4,9,9 and 1 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1374991-22:
(9*1)+(8*3)+(7*7)+(6*4)+(5*9)+(4*9)+(3*1)+(2*2)+(1*2)=196
196 % 10 = 6
So 1374991-22-6 is a valid CAS Registry Number.

Efficient synthesis of kaempferol 3,7-O-bisglycosides via successive glycosylation with glycosyl ortho-alkynylbenzoates and trifluoroacetimidates

Yang, Weizhun,Sun, Jiansong,Yang, Zhongyi,Han, Wei,Zhang, Wei-Dong,Yu, Biao

, p. 2773 - 2776 (2012/07/17)

Selective glycosylation of the 3-OH of 5,4′-di-O-acetyl-kaempferol was achieved with glycosyl ortho-alkynylbenzoates as donors under the catalysis of Ph3PAuNTf2, and subsequent glycosylation of the remaining 7-OH with glycosyl triflu
