Check Digit Verification of cas no

The CAS Registry Mumber 1253404-34-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,3,4,0 and 4 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1253404-34:
(9*1)+(8*2)+(7*5)+(6*3)+(5*4)+(4*0)+(3*4)+(2*3)+(1*4)=120
120 % 10 = 0
So 1253404-34-0 is a valid CAS Registry Number.

Novel Prolinamide Organocatalysts Based on Calix[4]arene Scaffold for the Enantioselective Direct Aldol Reaction

Li, Zheng-Yi,Lu, Cheng-Xi,Huang, Guoli,Ma, Jie-Jie,Sun, Hongsheng,Wang, Leyong,Pan, Yi

, p. 461 - 466 (2011/09/14)

A series of novel prolinamide organocatalysts based on calix[4]arene scaffold have been developed to catalyze the direct asymmetric aldol reaction of aromatic aldehydes and cyclohexanone. Under the optimal condition, high isolated yields (up to 99%) and enantioselectivities (up to 97% ee), and moderate diastereoselectivities (up to 85/15) were obtained.
