134668-20-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 134668-20-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,6,6 and 8 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 134668-20:
(8*1)+(7*3)+(6*4)+(5*6)+(4*6)+(3*8)+(2*2)+(1*0)=135
135 % 10 = 5
So 134668-20-5 is a valid CAS Registry Number.

A Novel Application of Sodium Borohydride for the Regiospecific and Stereoselective Reduction of Conjugated Alkadiynes
Thyagarajan, Budalur S.,Chandler, Richard,Santillan, Alejandro
, p. 3477 - 3488 (2007/10/02)
Alkynes, when carrying an α-sulfonyl group, are shown to be stereoselectively reduced to z-alkenes using sodium borohydride under mildly conditions.
