Check Digit Verification of cas no

The CAS Registry Mumber 117402-90-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,4,0 and 2 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 117402-90:
(8*1)+(7*1)+(6*7)+(5*4)+(4*0)+(3*2)+(2*9)+(1*0)=101
101 % 10 = 1
So 117402-90-1 is a valid CAS Registry Number.

SOLID-LIQUID PHASE TRANSFER CATALYSTS WITHOUT SOLVENT : AN IMPROVEMENT FOR CHIRAL MICHAEL ADDITION OF N-ACETYLAMINOMALONATE TO CHALCONE

Loupy, Andre,Sansoulet, Jean,Zaparucha, Anne,Merienne, Claude

, p. 333 - 336 (1989)

Solid-liquid phase transfer catalysis (PTC) without added solvent efficiently promotes chiral Michael addition when the reaction is achieved in presence of quaternary salts derived from (+) or (-) N-methyl ephedrine. enantiomeric excesses are significantl
