Check Digit Verification of cas no

The CAS Registry Mumber 149559-55-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,9,5,5 and 9 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 149559-55:
(8*1)+(7*4)+(6*9)+(5*5)+(4*5)+(3*9)+(2*5)+(1*5)=177
177 % 10 = 7
So 149559-55-7 is a valid CAS Registry Number.

Free radical addition reactions of allylic sulfones to alkenes

Harvey, Iain W.,Phillips, Eifion D.,Whitham, Gordon H.

, p. 6493 - 6508 (1997)

Intermolecular radical reactions involving formal addition of the sulfonyl and allyl fragments of an allylic sulfone across the double bond of an alkene are described. Reactions are most successful when the allylic sulfone has an electron withdrawing group at the 2-position. Only monosubstituted alkenes give useful yields of adducts, though both electron withdrawing and electron donating substituents are effective.
