Check Digit Verification of cas no

The CAS Registry Mumber 1338236-51-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,8,2,3 and 6 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1338236-51:
(9*1)+(8*3)+(7*3)+(6*8)+(5*2)+(4*3)+(3*6)+(2*5)+(1*1)=153
153 % 10 = 3
So 1338236-51-3 is a valid CAS Registry Number.

Enantioselective copper-catalyzed alkynylation of benzopyranyl oxocarbenium ions

Srinivas, Harathi D.,Maity, Prantik,Yap, Glenn P. A.,Watson, Mary P.

, p. 4003 - 4016 (2015/09/07)

We have developed highly enantioselective, copper-catalyzed alkynylations of benzopyranyl acetals. By using a copper(I) catalyst equipped with a chiral bis(oxazoline) ligand, high yields and enantioselectivities are achieved in the alkynylation of widely
