Check Digit Verification of cas no

The CAS Registry Mumber 2204-64-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,2,0 and 4 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 2204-64:
(6*2)+(5*2)+(4*0)+(3*4)+(2*6)+(1*4)=50
50 % 10 = 0
So 2204-64-0 is a valid CAS Registry Number.

Cycloadditions of Ynamines with α,β-Unsaturated Sulfones: Approach to Versatile Four-Membered Carbocyclic Intermediates

Eisch, John J.,Galle, James E.,Hallenbeck, Lawrence E.

, p. 1608 - 1610 (2007/10/02)

The interaction of ynamines with various α,β-unsaturated sulfones, such as 1-alkenyl, 1-alkynyl, or 1,3-alkadienyl sulfones, leads to the ready formation of the vicinally amino- and sulfonyl-substituted cyclobuta ring in a regiospecific manner.The resulti
