Check Digit Verification of cas no

The CAS Registry Mumber 213533-33-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,3,5,3 and 3 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 213533-33:
(8*2)+(7*1)+(6*3)+(5*5)+(4*3)+(3*3)+(2*3)+(1*3)=96
96 % 10 = 6
So 213533-33-6 is a valid CAS Registry Number.

1,3-Bis(phenylsulfonyl)allene as a new reagent for cycloaddition methodology

Bull, James R.,Desmond-Smith, Nicholas S.,Heggie, Steven J.,Hunter, Roger,Tien, Feng-Chang

, p. 900 - 902 (2007/10/03)

1,3-Bis(phenylsulfonyl)allene 2 has been synthesised as a new reagent for cycloaddition methodology. In contrast to phenylsulfonylallene 1, thermal reaction of 2 with substituted 1,3-dienes gave both [2+2] as well as [2+4] cycloaddition products.
