Check Digit Verification of cas no

The CAS Registry Mumber 93432-15-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,4,3 and 2 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 93432-15:
(7*9)+(6*3)+(5*4)+(4*3)+(3*2)+(2*1)+(1*5)=126
126 % 10 = 6
So 93432-15-6 is a valid CAS Registry Number.

Protective opening of epoxide using pivaloyl halides under catalyst-free conditions

Rao, Chitturi Bhujanga,Rao, Dasireddi Chandra,Venkateswara, Mallem,Venkateswarlu, Yenamandra

supporting information; experimental part, p. 2704 - 2707 (2011/12/05)

An efficient and environmentally benign protocol for protective opening of epoxide (POE) with pivaloyl halides in solvent-free conditions and in aqueous media under catalyst-free conditions has been developed. The green reaction conditions, simple work-up procedures, high yields and broad scope of the reaction illustrate the good synthetic utility of this method. The key advantages of the reaction are regioselectivity and reconvertability of products into their prior epoxides in the presence of mild reaction conditions.
