Check Digit Verification of cas no
The CAS Registry Mumber 20498-65-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,4,9 and 8 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 20498-65:
(7*2)+(6*0)+(5*4)+(4*9)+(3*8)+(2*6)+(1*5)=111
111 % 10 = 1
So 20498-65-1 is a valid CAS Registry Number.

Chemoselective Benzylation of Aldehydes Using Lewis Base Activated Boronate Nucleophiles
Hollerbach, Michael R.,Barker, Timothy J.
, p. 1425 - 1427 (2018/05/24)
A benzylation of aldehydes using primary and secondary benzylboronic acid pinacol esters is reported. Activation of the boronic ester with s-butyllithium rendered it nucleophilic toward aldehydes. The activated nucleophile chemoselectively transfers the benzyl group over the sec-butyl group, providing excellent yields of the benzylated products. 11B NMR experiments were performed to study the mechanism of this transformation.
