Check Digit Verification of cas no

The CAS Registry Mumber 855272-22-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,5,2,7 and 2 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 855272-22:
(8*8)+(7*5)+(6*5)+(5*2)+(4*7)+(3*2)+(2*2)+(1*2)=179
179 % 10 = 9
So 855272-22-9 is a valid CAS Registry Number.

An efficient of Grignard-type procedure for the preparation of gem-diallylated compound

Shen, Kao-Hsien,Kuo, Chun-Wei,Yao, Ching-Fa

, p. 6348 - 6351 (2007)

An efficient and a new procedure for the conversion of various carboxylic acid derivatives into the corresponding gem-diallylated compound under mild reaction condition has been developed. The triallylaluminum mediated Grignard-type addition of carboxylic acid derivative was utilized as a key operation to affect the transformation. The procedure is operationally simple, giving good to excellent product yields for a broad range of substrates. The chemoselectivity and regioselectivity of triallylaluminum were also demonstrated.

Generation of allyl Grignard reagents via titanocene-catalyzed activation of allyl halides

Fleury, Lauren M.,Ashfeld, Brandon L.

supporting information; experimental part, p. 2427 - 2430 (2010/07/04)

A protocol for the generation of allyl Grignard reagents via the catalytic activation of allyl halides is described herein. Subsequent nucleophilic addition to carbonyl derivatives provided the desired homo allylic alcohols in excellent yields (84-99%). E
