Check Digit Verification of cas no

The CAS Registry Mumber 1394134-51-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,9,4,1,3 and 4 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1394134-51:
(9*1)+(8*3)+(7*9)+(6*4)+(5*1)+(4*3)+(3*4)+(2*5)+(1*1)=160
160 % 10 = 0
So 1394134-51-0 is a valid CAS Registry Number.

Intramolecular direct dehydrohalide coupling promoted by KOtBu: Total synthesis of amaryllidaceae alkaloids anhydrolycorinone and oxoassoanine

De, Subhadip,Ghosh, Santanu,Bhunia, Subhajit,Sheikh, Javeed Ahmad,Bisai, Alakesh

, p. 4466 - 4469 (2012)

A transition-metal-free intramolecular dehydrohalide coupling via intramolecular homolytic aromatic substitution (HAS) with aryl radicals has been developed in the presence of potassium tert-butoxide and an organic molecule as the catalyst. The methodology has been applied to a concise synthesis of Amaryllidaceae alkaloids viz. oxoassoanine (1b), anhydrolycorinone (1d), and other related structures. Interestingly, the method also works only in the presence of potassium tert-butoxide.
