Check Digit Verification of cas no

The CAS Registry Mumber 1609939-34-5 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, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1609939-34:
(9*1)+(8*6)+(7*0)+(6*9)+(5*9)+(4*3)+(3*9)+(2*3)+(1*4)=205
205 % 10 = 5
So 1609939-34-5 is a valid CAS Registry Number.

Access to divergent benzo-heterocycles: Via a catalyst-dependent strategy in the controllable cyclization of o -alkynyl- N -methoxyl-benzamides

Ding, Dong,Mou, Tao,Xue, Jiahui,Jiang, Xuefeng

, p. 5279 - 5282 (2017)

A chemo- and regio-selectively controllable approach for construction of diverse benzo-heterocycles is established. A new strategy for using the ligand effect in gold catalysis to control the regioselectivity in the cyclization of o-alkynyl-N-methoxyl-benzamide is successfully achieved. Meanwhile, the chemoselectivity between nitrogen and oxygen nucleophiles is precisely switched by gold and platinum catalysts.

Rhodium(III)-catalyzed chemodivergent annulations between: N-methoxybenzamides and sulfoxonium ylides via C-H activation

Xu, Youwei,Zheng, Guangfan,Yang, Xifa,Li, Xingwei

supporting information, p. 670 - 673 (2018/01/28)

Chemodivergent and redox-neutral annulations between N-methoxybenzamides and sulfoxonium ylides have been realized via Rh(iii)-catalyzed C-H activation. The sulfoxonium ylide acts as a carbene precursor, and coupling occurs under acid-controlled condition
