596819-81-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 596819-81-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,9,6,8,1 and 9 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 596819-81:
(8*5)+(7*9)+(6*6)+(5*8)+(4*1)+(3*9)+(2*8)+(1*1)=227
227 % 10 = 7
So 596819-81-7 is a valid CAS Registry Number.

Facile synthesis of diarylpyrazines using suzuki coupling of dichloropyrazines with aryl boronic acids
Schultheiss, Nate,Bosch, Eric
, p. 1891 - 1897 (2007/10/03)
The palladium-catalyzed coupling of dichloropyrazines with aryl boronic acids is reported. The reaction proceeds smoothly under anaerobic conditions to give moderate to good yields of the corresponding diarylpyrazines.
