138154-68-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 138154-68-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,1,5 and 4 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 138154-68:
(8*1)+(7*3)+(6*8)+(5*1)+(4*5)+(3*4)+(2*6)+(1*8)=134
134 % 10 = 4
So 138154-68-4 is a valid CAS Registry Number.

Murakami, Masahiro,Hayashi, Minoru,Ito, Yoshihiko
, p. 793 - 794 (2007/10/02)
Treatment of a tertiary amine having a pendent o-iodobenzyl group on nitrogen with SmI2 generates α-amino organosamarium, which reacts with electrophiles giving the corresponding C-C bond formation products in good yield.
