1301262-04-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1301262-04-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,0,1,2,6 and 2 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1301262-04:
(9*1)+(8*3)+(7*0)+(6*1)+(5*2)+(4*6)+(3*2)+(2*0)+(1*4)=83
83 % 10 = 3
So 1301262-04-3 is a valid CAS Registry Number.

A short and efficient Julia-Kocienski olefination protocol, based upon the use of chelating agents (18-crown-6 or TDA-1 for K+; 12-crown-4 or HMPA for Li+), was developed. This protocol enhances the (E)-selectivity of the reaction an
