Check Digit Verification of cas no

The CAS Registry Mumber 297734-22-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,9,7,7,3 and 4 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 297734-22:
(8*2)+(7*9)+(6*7)+(5*7)+(4*3)+(3*4)+(2*2)+(1*2)=186
186 % 10 = 6
So 297734-22-6 is a valid CAS Registry Number.

experimental part, p. 5049 - 5055 (2012/09/22)

The development of a novel palladium-catalysed amidation approach towards 5,7,8,9-tetrahydropyrimido[4,5-b][1,4]diazepin-6-one templates is highlighted. The route proceeds through the reaction of an amino amide, generated by 1,4-addition of an amine to an
