Check Digit Verification of cas no

The CAS Registry Mumber 197916-07-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,7,9,1 and 6 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 197916-07:
(8*1)+(7*9)+(6*7)+(5*9)+(4*1)+(3*6)+(2*0)+(1*7)=187
187 % 10 = 7
So 197916-07-7 is a valid CAS Registry Number.

Highly regioselective and stereoselective synthesis of C-Aryl glycosidesvianickel-catalyzedortho-C-H glycosylation of 8-aminoquinoline benzamides

Chen, Xi,Ding, Ya-Nan,Gou, Xue-Ya,Liang, Yong-Min,Luan, Yu-Yong,Niu, Zhi-Jie,Shi, Wei-Yu,Zhang, Zhe,Zheng, Nian

, p. 8945 - 8948 (2021)

C-Aryl glycosides are of high value as drug candidates. Here a novel and cost-effective nickel catalyzedortho-CAr-H glycosylation reaction with high regioselectivity and excellent α-selectivity is described. This method shows great functional group compatibility with various glycosides, showing its synthetic potential. Mechanistic studies indicate that C-H activation could be the rate-determining step.

Facile glycosylation strategy with two-stage activation of allyl glycosyl donors. Application to concise synthesis of Shigella flexneri serotype y O-antigen

Wang, Yun,Zhang, Xin,Wang, Pengfei

supporting information; experimental part, p. 4322 - 4328 (2010/11/18)

A practical, useful glycosylation method employing only allyl glycoside building blocks has been developed. The donor's glycosylation reactivity is turned on via isomerization of its anomeric allyl protecting group into the corresponding prop-1-enyl moiet
