Check Digit Verification of cas no

The CAS Registry Mumber 1240510-84-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,0,5,1 and 0 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1240510-84:
(9*1)+(8*2)+(7*4)+(6*0)+(5*5)+(4*1)+(3*0)+(2*8)+(1*4)=102
102 % 10 = 2
So 1240510-84-2 is a valid CAS Registry Number.

Palladium-catalyzed synthesis of enantiomerically pure α-substituted allylboronic esters and their addition to aldehydes

Fernandez, Enrique,Pietruszka, Joerg,Frey, Wolfgang

supporting information; experimental part, p. 5580 - 5589 (2010/11/17)

Tartrate-derived boronic esters 2 can be subjected to palladium-catalyzed carbonyl allylations with SnCl2 to obtain enantiomerically pure α-substituted allylboronic esters 8 and 9. The reaction proceeds regioselectively and with high, simple diastereoselectivity to form anti-products. Their addition to aldehydes yields enantiomerically enriched homoallylic alcohols 17 and 18, respectively. Synthesis, characterization, and a mechanistic rational is presented here.
