Check Digit Verification of cas no

The CAS Registry Mumber 1606131-61-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,0,6,1,3 and 1 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1606131-61:
(9*1)+(8*6)+(7*0)+(6*6)+(5*1)+(4*3)+(3*1)+(2*6)+(1*1)=126
126 % 10 = 6
So 1606131-61-6 is a valid CAS Registry Number.

Sequential C3 and C5 direct C-H arylation of imidazo[1,2-a]pyrazines with (Hetero)aryl bromides

Johnson, Brett M.,Huestis, Malcolm P.

, p. 1589 - 1593 (2014/03/21)

An efficient reaction manifold for the preparation of C3/C5- diarylimidazo[1,2-a]pyrazines through sequential C3 and C5 direct arylation is disclosed. The two distinct palladium catalyst systems showcased herein are compatible with a wide variety of aryl and heteroaryl bromides and are also operative in a one-pot, twofold C-H functionalization event.
