403670-55-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 403670-55-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,3,6,7 and 0 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 403670-55:
(8*4)+(7*0)+(6*3)+(5*6)+(4*7)+(3*0)+(2*5)+(1*5)=123
123 % 10 = 3
So 403670-55-3 is a valid CAS Registry Number.

A new route to butane-1,2-diacetals and the development of alternative substitution patterns to facilitate differential protection of the products

Ley,Michel

, p. 1793 - 1795 (2001)

The utility of 2,3-dialkoxybutan-1,3-dienes as reagents for the protection of vicinal diols and α-hydroxy acids as their corresponding 1,2-diacetals is demonstrated together with their later deprotection under mild reaction conditions.

Preparation of enantiopure butane-2,3-diacetals of glycolic acid and alkylation reactions leading to α-hydroxyacid and amide derivatives

, p. 3608 - 3617 (2007/10/03)

The preparation of butane-2,3-diacetal protected glycolic acid and related systems is described together with highly selective alkylation reactions of (R,R) and (S,S) butanediacetal protected glycolic acid. These compounds are readily deprotected to give
