Check Digit Verification of cas no

The CAS Registry Mumber 183211-04-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,3,2,1 and 1 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 183211-04:
(8*1)+(7*8)+(6*3)+(5*2)+(4*1)+(3*1)+(2*0)+(1*4)=103
103 % 10 = 3
So 183211-04-3 is a valid CAS Registry Number.

, p. 12677 - 12698 (2007/10/03)

Various monocyclic 1,2-dithiines 6a,b,d-t were prepared via (Z,Z)-1,4-difunctionalized butadienes (4-11,19,20). A twisted cyclic structure A is unequivocally proved rather than of the ringopened valence isomer B. The reactivity of these 1,2-dithiines is d
