1376271-21-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1376271-21-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,6,2,7 and 1 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1376271-21:
(9*1)+(8*3)+(7*7)+(6*6)+(5*2)+(4*7)+(3*1)+(2*2)+(1*1)=164
164 % 10 = 4
So 1376271-21-4 is a valid CAS Registry Number.

Stereoselective propargylation of glycals with allenyltributyltin(IV) via a Ferrier type reaction

Drew, Mark D.,Wall, Mark C.,Kim, Joseph T.

, p. 2833 - 2836 (2012)

Stereoselective introduction of an unsubstituted propargyl group to various glycals was achieved using a Ferrier type reaction with allenyltributyltin(IV). The stereoselectivity was observed based on the conformational preference of glycals as well as steric control of rigid bicyclic systems.
