Check Digit Verification of cas no

The CAS Registry Mumber 1231890-91-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,1,8,9 and 0 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1231890-91:
(9*1)+(8*2)+(7*3)+(6*1)+(5*8)+(4*9)+(3*0)+(2*9)+(1*1)=147
147 % 10 = 7
So 1231890-91-7 is a valid CAS Registry Number.

, p. 348 - 364 (2015/02/05)

A series of novel reversible Btk inhibitors has been designed based on the structure of the recently reported preclinical drug RN486. The synthesis and SAR of these compounds are described. Among these derivatives, compound 16b was identified to be a potent and orally available reversible agent with satisfactory Btk enzymatic and cellular inhibition in vitro, as well as favorable PK properties and inhibition of arthritis in vivo.
