Check Digit Verification of cas no

The CAS Registry Mumber 1286209-59-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,6,2,0 and 9 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1286209-59:
(9*1)+(8*2)+(7*8)+(6*6)+(5*2)+(4*0)+(3*9)+(2*5)+(1*9)=173
173 % 10 = 3
So 1286209-59-3 is a valid CAS Registry Number.

Oxidation of 1-benzyldihydroisoquinolines or 1- benzyltetrahydroisoquinolines with dioxygen to 1-benzoylisoquinolines

Gan, Haifeng,Lu, Yunyu,Huang, Yue,Ni, Lijun,Xu, Jinyi,Yao, Hequan,Wu, Xiaoming

experimental part, p. 1320 - 1324 (2011/04/15)

An environmental-benign methodology to synthesize 1-benzoylisoquinolines from 1-benzyl-3, 4-dihydroisoquinolines or 1-benzyl-1,2,3,4- tetrahydroisoquinolines using dioxygen as an oxidant was developed. This methodology in combination with Bischler-Napieralski reaction leads to a facile synthesis of 1-benzoylisoquinolines from phenylacetic acids and phenylethanamines.
