Check Digit Verification of cas no
The CAS Registry Mumber 111923-13-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,9,2 and 3 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 111923-13:
(8*1)+(7*1)+(6*1)+(5*9)+(4*2)+(3*3)+(2*1)+(1*3)=88
88 % 10 = 8
So 111923-13-8 is a valid CAS Registry Number.

THE SYNTHESIS OF THE ISOQUINOLINE ALKALOID CALYCOTOMINE VIA FUNCTIONALIZATION OF ENAMIDE DOUBLE BONDS
Lenz, George R.
, p. 721 - 730 (2007/10/02)
The novel alkaloid calycotomine, a 1-hydroxymethylenetetrahydroisoquinoline, has been synthesized from 1-methyl-3,4-dihydroisoquinoline via the 2-benzyloxycarbonyl enamide derivative.Oxidation of the enamide with osmium tetroxide results in bis-hydroxylat
