20706-73-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 20706-73-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,7,0 and 6 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 20706-73:
(7*2)+(6*0)+(5*7)+(4*0)+(3*6)+(2*7)+(1*3)=84
84 % 10 = 4
So 20706-73-4 is a valid CAS Registry Number.

An efficient method for deprotection of acetals
Saravanan,Chandrasekhar,Anand, R. Vijaya,Singh, Vinod K.
, p. 3091 - 3092 (2007/10/03)
A variety of acetonides and acetals were efficiently cleaved using CuCl2.2H2O in MeCN. The method was effectively used in synthesis of chiral diols which are important in asymmetric synthesis.
