Check Digit Verification of cas no

The CAS Registry Mumber 652150-92-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,5,2,1,5 and 0 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 652150-92:
(8*6)+(7*5)+(6*2)+(5*1)+(4*5)+(3*0)+(2*9)+(1*2)=140
140 % 10 = 0
So 652150-92-0 is a valid CAS Registry Number.

Catalytic Asymmetric Acyl Halide-Aldehyde Cyclocondensation Reactions of Substituted Ketenes

Nelson, Scott G.,Zhu, Cheng,Shen, Xiaoqiang

, p. 14 - 15 (2007/10/03)

Catalytic asymmetric acyl halide-aldehyde cyclocondensation (AAC) reactions of alkyl-substituted ketenes with structurally diverse aldehydes provide cis-disubstituted β-lactones with high enantioselectivity. The AAC reactions utilize a novel Al(III)-triamine catalyst in which the metal′s dynamic coordination geometry leads to a highly selective catalyst complex. These AAC reactions represent a functional solution to highly enantioselective substituted ester enolate aldol additions. Copyright
