Check Digit Verification of cas no

The CAS Registry Mumber 1188287-36-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,8,2,8 and 7 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1188287-36:
(9*1)+(8*1)+(7*8)+(6*8)+(5*2)+(4*8)+(3*7)+(2*3)+(1*6)=196
196 % 10 = 6
So 1188287-36-6 is a valid CAS Registry Number.

Visible-Light-Induced Cyclization of Electron-Enriched Phenyl Benzyl Sulfides: Synthesis of Tetrahydrofurans and Tetrahydropyrans

Li, Wei,Yang, Chao,Gao, Guo-Lin,Xia, Wujiong

, p. 1391 - 1396 (2016)

A new approach to the preparation of tetrahydrofurans and tetrahydropyrans through a photoredox catalytic process is described. The introduction of a phenylsulfanyl auxiliary group permits the substrates to be readily oxidized to form cationic intermediates for sequential intramolecular cyclization. The method features mild reaction conditions and operational simplicity.
