Check Digit Verification of cas no

The CAS Registry Mumber 187030-98-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,7,0,3 and 0 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 187030-98:
(8*1)+(7*8)+(6*7)+(5*0)+(4*3)+(3*0)+(2*9)+(1*8)=144
144 % 10 = 4
So 187030-98-4 is a valid CAS Registry Number.

Dipolar cycloaddition route to diverse analogues of cocaine: The 6- and 7-substituted 3-phenyltropanes

Kozikowski, Alan P.,Araldi, Gian Luca,Ball, Richard G.

, p. 503 - 509 (2007/10/03)

In our quest for an antagonist or partial agonist of cocaine, access to certain 6- and 7-substituted 3-phenyltropanes of type I was required. Starting from 3-hydroxy-1-methyl-4-phenylpyridinium iodide, we disclose a pyridinium betaine-based dipolar cycloaddition route to tropenones of type II. In turn, we show how this intermediate can be transformed to type I products either through the copper-catalyzed conjugate addition reaction of Grignard reagents to the enones 7-9 or by the copper(I)-catalyzed cross coupling reaction of the allylic acetates 15a and 16a with Grignard reagents.
