Check Digit Verification of cas no

The CAS Registry Mumber 129151-80-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,1,5 and 1 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 129151-80:
(8*1)+(7*2)+(6*9)+(5*1)+(4*5)+(3*1)+(2*8)+(1*0)=120
120 % 10 = 0
So 129151-80-0 is a valid CAS Registry Number.

Phase-transfer catalyzed glycolate conjugate addition

Andrus, Merritt B.,Ye, Zhifeng

, p. 534 - 537 (2008)

Cinchonine based phase-transfer catalysts were developed for enantioselective conjugate additions to electron deficient alkenes, including acylates, acrylonitrile, and chalcone. N-Trifulorobenzyl cinchoninium bromide 6 catalyst (20 mol %) in THF at -40 °C promoted the conjugate addition of arylketone glycolate 1 generating S-product 2 in good yields and selectivities. Catalyst, solvent, and base variations are presented along with conditions to convert the products to intermediates useful for multistep applications.
