Check Digit Verification of cas no

The CAS Registry Mumber 138469-70-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,4,6 and 9 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 138469-70:
(8*1)+(7*3)+(6*8)+(5*4)+(4*6)+(3*9)+(2*7)+(1*0)=162
162 % 10 = 2

THE USE OF o-MITROARYLACETONITRILES IN THE MITSUNOBU REACTION: MECHANISTIC IMPLICATIONS AND SYNTHETIC APPLICATIONS

Macor, John E.,Wehner, Jennifer M.

, p. 349 - 365 (2007/10/02)

o-Nitroarylacetonitriles (1) have been used as carbon acid participants in the Mitsunobu reaction to yield 2-(o-nitroaryl)-2-alkylacetonitriles (2).Reductive cyclization of 2 afforded 3-alkylindoles (3) in moderate yield.The use of o-nitroarylacetonitrile
