Check Digit Verification of cas no

The CAS Registry Mumber 37903-94-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,7,9,0 and 3 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 37903-94:
(7*3)+(6*7)+(5*9)+(4*0)+(3*3)+(2*9)+(1*4)=139
139 % 10 = 9
So 37903-94-9 is a valid CAS Registry Number.

Cascade palladium catalysis: A predictable and selectable regiocontrolled synthesis of N-arylbenzimidazoles

Jui, Nathan T.,Buchwald, Stephen L.

supporting information, p. 11624 - 11627 (2013/11/06)

By choice: The palladium-catalyzed cascade reaction of 2-chloroaryl sulfonates with arylamine and amide nucleophiles provides direct access to N-arylbenzimidazoles. This strategy selectively produces the heterocycles based on chemoselective oxidative addi
