69643-34-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 69643-34-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,6,4 and 3 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 69643-34:
(7*6)+(6*9)+(5*6)+(4*4)+(3*3)+(2*3)+(1*4)=161
161 % 10 = 1
So 69643-34-1 is a valid CAS Registry Number.

Synthesis of 3-alkyl-4-aryl- and 3,4-diaryl-1,2,5-thiadiazoles via palladium-catalyzed cross-coupling reaction
Hanasaki, Yasuaki
, p. 2435 - 2441 (2007/10/03)
4-Substituted 3-aryl-1,2,5-thiadiazoles were synthesized by palladium-catalyzed cross-coupling reaction of arylstannane with easily available 4-substituted 3-halogeno- and 3-trifluoromethylsulfonyloxy-1,2,5-thiadiazoles.
