Check Digit Verification of cas no

The CAS Registry Mumber 140835-51-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,8,3 and 5 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 140835-51:
(8*1)+(7*4)+(6*0)+(5*8)+(4*3)+(3*5)+(2*5)+(1*1)=114
114 % 10 = 4
So 140835-51-4 is a valid CAS Registry Number.

Acylnitrilium ion initiated heteroannulations in alkaloid synthesis. An efficient, stereocontrolled, total synthesis of the Orchidaceae alkaloid (±)-dendrobine

Lee, Cheol Hae,Westling, Mark,Livinghouse, Tom,Williams, Andrew C.

, p. 4089 - 4095 (1992)

A concise total synthesis of (±)-dendrobine is described that proceeds in eight steps from 2-methylcyclopent-2-en-1-one. The key transformation in this approach is the silver ion mediated cyclocondensation of the isonitrile 6 with the acyl chloride 5. Thi
