Check Digit Verification of cas no

The CAS Registry Mumber 1609939-61-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,0,9,9,3 and 9 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1609939-61:
(9*1)+(8*6)+(7*0)+(6*9)+(5*9)+(4*3)+(3*9)+(2*6)+(1*1)=208
208 % 10 = 8
So 1609939-61-8 is a valid CAS Registry Number.

Ru (II)-Catalyzed Coupling-Cyclization of Sulfoximines with alpha-Carbonyl Sulfoxonium Ylides as an Approach to 1,2-Benzothiazines

Xie, Haisheng,Lan, Jianyong,Gui, Jiao,Chen, Fengjuan,Jiang, Huangfeng,Zeng, Wei

, p. 3534 - 3543 (2018/08/06)

A Ru(II)-catalyzed approach for the rapid assembly of 1,2-benzothiazines has been developed to enable the coupling-cyclization of aryl Csp2?H bonds with α-carbonyl sulfoxonium ylides via Csp2?H activation process. The present method could be further applied to the construction of the 4-substituted 1,2-benzothiazine skeletons. (Figure presented.).
