Check Digit Verification of cas no

The CAS Registry Mumber 53244-20-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,3,2,4 and 4 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 53244-20:
(7*5)+(6*3)+(5*2)+(4*4)+(3*4)+(2*2)+(1*0)=95
95 % 10 = 5
So 53244-20-5 is a valid CAS Registry Number.

Photoinduced 1,2-Hydro(cyanomethylation) of Alkenes with a Cyanomethylphosphonium Ylide

Miura, Tomoya,Moriyama, Daisuke,Funakoshi, Yuuta,Murakami, Masahiro

, p. 511 - 514 (2019)

An efficient method has been developed for the 1,2-hydro(cyanomethylation) of alkenes, in which a cyanomethyl radical species is generated from a cyanomethylphosphonium ylide by irradiation with visible light in the presence of an iridium complex, a thiol, and ascorbic acid. The cyanomethyl radical species then adds across the C=C double bond of an alkene to form an elongated alkyl radical species that accepts a hydrogen atom from the thiol to produce an elongated aliphatic nitrile. The ascorbic acid acts as the reductant to complete the catalytic cycle.
