Check Digit Verification of cas no

The CAS Registry Mumber 143716-10-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,7,1 and 6 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 143716-10:
(8*1)+(7*4)+(6*3)+(5*7)+(4*1)+(3*6)+(2*1)+(1*0)=113
113 % 10 = 3
So 143716-10-3 is a valid CAS Registry Number.

Efficient Selenation of Quinones: Synthesis of Novel Benzonaphthoselenintrione and Dibenzoseleninone

Sakakibara, Makoto,Toru, Takeshi,Imai, Takahiro,Watanabe, Yoshihiko,Ueno, Yoshio

, p. 1291 - 1294 (2007/10/02)

Selenation of 2-bromonaphthoquinone with an areneselenolate ion generated from bis(2-methoxycarbonylphenyl) diselenide, chlorodiphenylphosphine, and LiOH afforded 2--1,4-naphthoquinone from which 12H-benzonaphthoselenin-6,11,12-trione was synthesized. 1,4-Dimethoxy-2,3-dimethyl-10H-dibenzoselenin-10-one was prepared starting from 6-bromo-2,3-dimethylbenzoquinone through the selenation and cyclization steps.
