Check Digit Verification of cas no

The CAS Registry Mumber 1642594-41-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,4,2,5,9 and 4 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1642594-41:
(9*1)+(8*6)+(7*4)+(6*2)+(5*5)+(4*9)+(3*4)+(2*4)+(1*1)=179
179 % 10 = 9
So 1642594-41-9 is a valid CAS Registry Number.

A convenient enantioselective decarboxylative aldol reaction to access chiral a-hydroxy esters using β-keto acids

Duan, Zhiqiang,Han, Jianlin,Qian, Ping,Zhang, Zirui,Wang, Yi,Pan, Yi

supporting information, p. 969 - 974 (2014/05/20)

We show a convenient decarboxylative aldol process using a scandium catalyst and a PYBOX ligand to generate a series of highly functionalized chiral a-hydroxy esters. The protocol tolerates a broad range of β-keto acids with inactivated aromatic and aliphatic a-keto esters. The possible mechanism is rationalized.
