143996-59-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 143996-59-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,9,9 and 6 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 143996-59:
(8*1)+(7*4)+(6*3)+(5*9)+(4*9)+(3*6)+(2*5)+(1*9)=172
172 % 10 = 2
So 143996-59-2 is a valid CAS Registry Number.

Tunable carbon-carbon and carbon-sulfur cross-coupling of boronic acids with 3,4-dihydropyrimidine-2-thiones
Lengar, Alenka,Kappe, C. Oliver
, p. 771 - 774 (2004)
Direct microwave-assisted Pd(0)-catalyzed/Cu(I)-mediated carbon-carbon cross-coupling of 3,4-dihydropyrimidine-2-thiones and boronic acids under Liebeskind-Srogl conditions leads to 2-aryl-1,4-dihydropyrimidines in moderate to high yield. In contrast, Cu(
