Check Digit Verification of cas no

The CAS Registry Mumber 947740-36-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,7,7,4 and 0 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 947740-36:
(8*9)+(7*4)+(6*7)+(5*7)+(4*4)+(3*0)+(2*3)+(1*6)=205
205 % 10 = 5
So 947740-36-5 is a valid CAS Registry Number.

Diphenylprolinol silyl ether as a catalyst in an enantioselective, catalytic, tandem Michael/Henry reaction for the control of four stereocenters

Hayashi, Yujiro,Okano, Tsubasa,Aratake, Seiji,Hazelard, Damien

, p. 4922 - 4925 (2007)

(Chemical Equation Presented) A choice of three: The tandem Michael/ Henry reaction of a nitroalkene and pentane-1,5-dial (generated in situ) proceeded efficiently when diphenylprolinol silyl ether was used as an organocatalyst to afford substituted nitrocyclohexanecarbaldehydes with high diastereo- and enantioselectivity (see scheme; TMS: trimethylsilyl). Isomerization under basic or acidic conditions diastereoselectively converts the product into two stereoisomers, without compromising the enantioselectivity.
