Check Digit Verification of cas no

The CAS Registry Mumber 1029289-40-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,9,2,8 and 9 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1029289-40:
(9*1)+(8*0)+(7*2)+(6*9)+(5*2)+(4*8)+(3*9)+(2*4)+(1*0)=154
154 % 10 = 4
So 1029289-40-4 is a valid CAS Registry Number.

supporting information; experimental part, p. 2231 - 2234 (2009/05/11)

(Chemicall Equation Presented) Stereodivergent construction of three contiguous stereocenters in catalytic doubly diastereoselective nitroaldol reactions of α-chiral aldehydes with nitroacetaldehyde dimethyl acetal using two types of heterobimetallic catalysts is described. A La-Li-BINOL (LLB) catalyst afforded anti,syn-nitroaldol products in >20:1-14:1 selectivity, and a Pd/La/Schiff base catalyst afforded complimentary syn,syn-nitroaldol products in 10:1-5:1 selectivity.
