Check Digit Verification of cas no

The CAS Registry Mumber 148273-16-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,8,2,7 and 3 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 148273-16:
(8*1)+(7*4)+(6*8)+(5*2)+(4*7)+(3*3)+(2*1)+(1*6)=139
139 % 10 = 9
So 148273-16-9 is a valid CAS Registry Number.

Synthesis and reactions of 2-alkylidene-1,3,4,-thiadiazolines and their selenium analogues

Choi, Nami,Tokitoh, Norihiro,Goto, Midori,Ando, Wataru

, p. 1189 - 1202 (1993)

2-Alkylidene-1,3,4-thiadiazoline 11a gave thioketone 16 (X=S) and acetylene derivative 17 on thermolysis via thiocarbonyl ylide, quantitatively. Pyrolysis of selenium analogue gave similar results. Allyl substituted 2-alkylidene-1,3,4-thiadiazolines 11a a
