Check Digit Verification of cas no

The CAS Registry Mumber 1043444-31-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,4,3,4,4 and 4 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1043444-31:
(9*1)+(8*0)+(7*4)+(6*3)+(5*4)+(4*4)+(3*4)+(2*3)+(1*1)=110
110 % 10 = 0
So 1043444-31-0 is a valid CAS Registry Number.

An improved synthesis of haloacetamidine-based inactivators of protein arginine deiminase 4 (PAD4)

Causey, Corey P.,Thompson, Paul R.

, p. 4383 - 4385 (2008)

Protein arginine deiminase 4 (PAD4) is an enzyme that hydrolyzes peptidyl arginine residues to form citrulline and ammonia. This enzyme has been implicated in several disease states, for example, rheumatoid arthritis, and therefore represents a unique target for the development of a novel therapeutic. A solution-phase synthesis of Cl-amidine, the most potent PAD4 inactivator described to date, has been developed. This synthesis proceeds in 80% yield over four steps at a significantly (12-fold) lower cost.
