Check Digit Verification of cas no

The CAS Registry Mumber 344746-97-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,4,7,4 and 6 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 344746-97:
(8*3)+(7*4)+(6*4)+(5*7)+(4*4)+(3*6)+(2*9)+(1*7)=170
170 % 10 = 0
So 344746-97-0 is a valid CAS Registry Number.

High regioselectivity in electrochemical α-methoxylation of N-protected cyclic amines

Libendi, Samuel S.,Demizu, Yosuke,Matsumura, Yoshihiro,Onomura, Osamu

, p. 3935 - 3942 (2008/09/20)

N-Protecting groups of α-substituted cyclic amines strongly affected the regioselectivity in electrochemical methoxylation of these compounds. Namely, N-acyl derivatives were transformed into α′-methoxylated compounds, while N-cyano derivatives changed into α-methoxylated derivatives. Furthermore, Lewis acid catalyzed nucleophilic substitution of the α-methoxylated compounds protected with cyano group afforded α,α-disubstituted cyclic amines.
