Check Digit Verification of cas no

The CAS Registry Mumber 114197-34-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,4,1,9 and 7 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 114197-34:
(8*1)+(7*1)+(6*4)+(5*1)+(4*9)+(3*7)+(2*3)+(1*4)=111
111 % 10 = 1
So 114197-34-1 is a valid CAS Registry Number.

Photochemical Reactions of Pyrimidinethiones with Alkenes

Nishio, Takehiki,Fujisawa, Masaru,Omote, Yoshimori

, p. 2523 - 2530 (2007/10/02)

Photochemical addition reactions of pyrimidinethiones and related compounds with alkenes have been examinated.Irradiation of pyrimidine-4(3H)-thiones (1a) in the presence of electron-poor alkenes gave the 4-mercaptoalkylated pyrimidines (5), whereas irradiation of (1a) in the presence of electron-rich alkenes gave 4-alkylthiopyrimidines (6).Irradiation of quinazoline-4(3H)-thiones (1c-e) and electron-poor alkenes gave 4-subtituted quinazolines (9) and (10).This ready mode of carbon-carbon bond formation provides an efficient and novel method for alkylation of pyrimidine rings.
