6667-26-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 6667-26-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,6,6 and 7 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 6667-26:
(6*6)+(5*6)+(4*6)+(3*7)+(2*2)+(1*6)=121
121 % 10 = 1
So 6667-26-1 is a valid CAS Registry Number.

Bromoacetyl bromide: A versatile and selective cleaving agent for ethers and acetals

Schneider, David F.,Viljoen, Murray S.

, p. 721 - 728 (2002)

It is shown that bromoacetyl bromide can be utilized for the selective cleavage of ethers and acetals in high yields. With cyclic ethers and acetals as starting materials, cleavage products are produced with two strategically positioned bromo substituents which may be exploited for selective extention of the carbon chain.
