Check Digit Verification of cas no

The CAS Registry Mumber 81747-47-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,7,4 and 7 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 81747-47:
(7*8)+(6*1)+(5*7)+(4*4)+(3*7)+(2*4)+(1*7)=149
149 % 10 = 9
So 81747-47-9 is a valid CAS Registry Number.

Thioacyl Isocyanates, XVII. Reaction of Ethoxy(thiocarbonyl) Isocyanate with Vinyl Ethers

Goerdeler, Joachim,Schulze, Andreas

, p. 1259 - 1264 (2007/10/02)

Ethoxy(thiocarbonyl) isocyanate (5) reacts with linear and cyclic vinyl ethers to give dihydro-1,3-thiazinones (1, 3, 6, 8) besides unsaturated carboxamides (2, 4, 7, 9).In some cases β-lactams in low concentrations probably originated (spectroscopy).The cycloaddition occurred regiospecifically according to the polarity; it afforded with dihydropyran the bicyclic compound 6 with cis bonded rings.
