Check Digit Verification of cas no

The CAS Registry Mumber 142138-83-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,1,3 and 8 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 142138-83:
(8*1)+(7*4)+(6*2)+(5*1)+(4*3)+(3*8)+(2*8)+(1*3)=108
108 % 10 = 8
So 142138-83-8 is a valid CAS Registry Number.

Organocatalyzed regioselective and enantioselective synthesis of 1,4- and 1,2-dihydropyridines

Le, Truong-Giang,Pham, Hoai-Thu,Martin, James P.,Chataigner, Isabelle,Renaud, Jean-Luc

, p. 2673 - 2684 (2020/08/07)

Herein, we introduce one of the first examples of asymmetric organocatalyzed synthesis of 1,2-dihydropyridines, affording enantioselective access to and partially solving regioselectivity challenges in the synthesis of dihydropyridines. We demonstrate that through modification of organocatalysts both 1,2- and 1,4-dihydropyridines (1,2- and 1,4-DHPs) can be obtained with high regioselectivity (ratio of 1,2-DHP/1,4-DHP from 95/5 to 0/100) and enantioselectivity (33% ee for 1,2-DHPs and up to 98% ee for 1,4-DHPs) in good yields (up to 87%).
