Check Digit Verification of cas no

The CAS Registry Mumber 50345-37-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,0,3,4 and 5 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 50345-37:
(7*5)+(6*0)+(5*3)+(4*4)+(3*5)+(2*3)+(1*7)=94
94 % 10 = 4
So 50345-37-4 is a valid CAS Registry Number.

Novel S-Alkylation Products from "Isolated Thiamin Ylide" via Thiaminium Neothiaminthiolate Ion Pair

Sugimoto, Hirohiko,Ishiba, Teruyuki,Sato, Tomohiro,Nakai, Hiroshi,Hirai, Kentaro

, p. 467 - 470 (2007/10/02)

The ambident anion character of thiamin ylide was demonstrated by alkylation reactions of the "isolated thiamin ylide" under neutral or basic conditions.Alkylation with alkyl halides yielded S-alkyl derivatives of the yellow form of thiamin (pyrimidopyrimidine derivatives) instead of 2-alkylthiamin.These and previous results provide chemical evidence that thiamin ylide and thiaminium neothiaminthiolate (8) undergo a facile interconversion in EtOH.
