1071-94-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1071-94-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,0,7 and 1 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1071-94:
(6*1)+(5*0)+(4*7)+(3*1)+(2*9)+(1*4)=59
59 % 10 = 9
So 1071-94-9 is a valid CAS Registry Number.

REACTION OF HOMOALLYLIC COMPOUNDS OF TIN WITH ACYLATING AGENTS

Ivashchenko, N. B.,Polunin, E. V.,Kashin, A. N.

, p. 546 - 550 (2007/10/02)

In the reaction of homoallylic organotin compounds with carboxylic acid anhydrides and chlorides in the presence of Lewis acids cyclopropyl methyl ketones are formed with α,β-unsaturated ketones and β-chloro ketones as impurities.The ratio of the reaction products depends on the temperature, the structure of the reagents, and the type of catalyst.
