Check Digit Verification of cas no

The CAS Registry Mumber 109257-45-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,2,5 and 7 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 109257-45:
(8*1)+(7*0)+(6*9)+(5*2)+(4*5)+(3*7)+(2*4)+(1*5)=126
126 % 10 = 6
So 109257-45-6 is a valid CAS Registry Number.

SELECTIVITY OF NUCLEOPHILIC ADDITION TO AND SUBSTITUTION AT ISOTHIOCYANATOCARBONYL GROUP. REACTIONS OF 4-PENTINOYL- AND 2-(2-PROPINYL)-4-PENTINOYL ISOTHIOCYANATE WITH AMINES AND METHANOL

Kutschy, Peter,Kristian, Pavol,Dzurilla, Milan,Koscik, Dusan,Nadaskay, Robert

, p. 995 - 1005 (2007/10/02)

4-Pentinoyl isothiocyanate reacts with primary and secondary amines by either nucleophilic addition to N=C=S group to yield the corresponding thioureas, or a nucleophilic substitution at the carbonyl group to give 4-pentinoic acid amides.The less nucleophilic diphenylamine reacts selectively to afford the product of nucleophilic addition only. 2-(2-Propinyl)-4-pentinoyl isothiocyanate, having a sterically hindered carbonyl group, furnished with primary amines a mixture of amides and thioureas, whereas the bulkier secondary amines react selectively to form thioureasonly.Both isothiocyanates afford with methanol as a nucleophile axclusively the corresponding O-methyl monothiocarbamates.
