Check Digit Verification of cas no

The CAS Registry Mumber 402849-49-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,2,8,4 and 9 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 402849-49:
(8*4)+(7*0)+(6*2)+(5*8)+(4*4)+(3*9)+(2*4)+(1*9)=144
144 % 10 = 4
So 402849-49-4 is a valid CAS Registry Number.

Bis-heteronucleophilic michael addition to divinyl sulfone: A new efficient access to macrocycles

Teyssot, Marie-Laure,Fayolle, Martine,Philouze, Christian,Dupuy, Claude

, p. 54 - 62 (2007/10/03)

The Michael addition of bis(nitrogen or sulfur) nucleophiles to divinyl sulfone provides the corresponding macrocyclic adducts in good yields. The structures of some new macrocyclic sulfones are established by X-ray crystallographic analysis and NMR spectroscopy. The subsequent cleavage of benzyl or tosyl groups yields the unprotected macrocyclic sulfones. Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003.
