Check Digit Verification of cas no

The CAS Registry Mumber 917951-47-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,7,9,5 and 1 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 917951-47:
(8*9)+(7*1)+(6*7)+(5*9)+(4*5)+(3*1)+(2*4)+(1*7)=204
204 % 10 = 4
So 917951-47-4 is a valid CAS Registry Number.

A palladium-catalysed urea arylation route to a CRF1 receptor antagonist

Popkin, Matthew E.,Bellingham, Richard K.,Hayes, Jerome F.

, p. 2716 - 2718 (2008/02/11)

A new synthetic approach to a potent CRF antagonist, GW808990 (NBI35583), is reported. The route hinges on the palladium-catalysed intramolecular arylation of a urea with 2-chloropyridine. Spontaneous piperazine ring closure means that a high-yielding bis
