Check Digit Verification of cas no

The CAS Registry Mumber 188000-43-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,8,0,0 and 0 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 188000-43:
(8*1)+(7*8)+(6*8)+(5*0)+(4*0)+(3*0)+(2*4)+(1*3)=123
123 % 10 = 3
So 188000-43-3 is a valid CAS Registry Number.

Asymmetric induction in a new domino reaction of [3,3]-sigmatropic rearrangement of allylic thiocyanates and intramolecular heterocyclisation

Gonda, Jozef,Martinková, Miroslava,Imrich, Ján

, p. 1611 - 1616 (2007/10/03)

A new synthetic route to diastereomerically pure (4S,5S)-4-vinyltetrahydro-1H-2-imidazolethiones via a novel domino reaction of [3,3]-sigmatropic rearrangement of chiral thiocyanates followed by stereoselective intramolecular amine addition to arising isothiocyanates is reported.
