Check Digit Verification of cas no

The CAS Registry Mumber 149419-72-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,9,4,1 and 9 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 149419-72:
(8*1)+(7*4)+(6*9)+(5*4)+(4*1)+(3*9)+(2*7)+(1*2)=157
157 % 10 = 7
So 149419-72-7 is a valid CAS Registry Number.

Komatsu, Naoki,Murakami, Tatsushi,Nishibayashi, Yoshiaki,Sugita, Toshio,Uemura, Sakae

, p. 3697 - 3702 (2007/10/02)

Asymmetric oxidation of some aryl vinyl selenides (3) with Sharpless (A-C), modified Sharpless (D) or Davis oxidants (E-G) resulted in the formation of chiral allenic sulfones 5 of up to 42percent enantiomeric excess (ee) via double asymmetric induction,
