Check Digit Verification of cas no

The CAS Registry Mumber 80287-80-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,2,8 and 7 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 80287-80:
(7*8)+(6*0)+(5*2)+(4*8)+(3*7)+(2*8)+(1*0)=135
135 % 10 = 5
So 80287-80-5 is a valid CAS Registry Number.

Fluoride-Mediated Reactions of Enol Silyl Ethers. Regiospecific Monoalkylation of Ketones

Kuwajima, Isao,Nakamura, Eiichi,Shimizu, Makoto

, p. 1025 - 1030 (1982)

Treatment of enol silyl ethers with alkyl halides in the presence of benzyltrimethylammonium fluoride and molecular sieves at room temperature gives the corresponding monoalkylated products with high regiospecificity.In most cases no polyalkylated products formed in the reaction.The alkylation reaction is highly chemospecific: esters, epoxides, and even ketones survive the reaction conditions.The reactions of various cyclohexanone derivatives proceed with the preferential axial attack of the electrophile.
