Check Digit Verification of cas no

The CAS Registry Mumber 1603837-72-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,0,3,8,3 and 7 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1603837-72:
(9*1)+(8*6)+(7*0)+(6*3)+(5*8)+(4*3)+(3*7)+(2*7)+(1*2)=164
164 % 10 = 4
So 1603837-72-4 is a valid CAS Registry Number.

Additive-free radical cascade reaction of oxime esters: Synthesis of pyrroline-functionalized phenanthridines

Shao, Liming,Xue, Yijie,Xue, Dengqi,He, Qian,Ge, Qianwei,Li, Wei

, p. 12284 - 12293 (2020/11/10)

A variety of dihydropyrrole-functionalized phenanthridines were efficiently synthesized by the metal-free, radical cascade cyclization reaction of 2-isocyanobiphenyls with γ,δ- unsaturated oxime esters. The C-N/C-C/C-C bonds were formed via the oil bath method in a one-pot procedure with broad substrate applicability. The radical process was supported by kinetic isotope effect studies and radical inhibition studies.
