Check Digit Verification of cas no

The CAS Registry Mumber 39761-61-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,7,6 and 1 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 39761-61:
(7*3)+(6*9)+(5*7)+(4*6)+(3*1)+(2*6)+(1*1)=150
150 % 10 = 0
So 39761-61-0 is a valid CAS Registry Number.

AN EASY SYNTHESIS OF THE 2-PHENYLSULFONYL-SUBSTITUTED ALLYLIC BROMIDES AND ACETATES AND THEIR REACTIVITY TOWARDS NUCLEOPHILES

Auvray, P.,Knochel, P.,Normant, J. F.

, p. 5095 - 5098 (2007/10/02)

The reaction of phenyl vinyl sulfone with various aldehydes in the presence of a catalytic amount of DABCO furnishes in good yields the corresponding 2-phenylsulfonyl-substituted alcohols 5a-5e which can be easily converted into their acetates 2a-2b or into their allylically rearranged bromides 3a-3d.These reagents, in turn, react with nucleophiles (ketone enolates and cuprates) with an allylic rearrangement (SN2' mechanism) to give the functionalized unsaturated sulfones 6a-g and 7a-g.A palladium catalyzed reaction allows a stereo-controlled transformation of the sulfone 6b into the (Z,Z) skipped 1,4-diene 8.
