Check Digit Verification of cas no

The CAS Registry Mumber 1416442-34-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,1,6,4,4 and 2 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1416442-34:
(9*1)+(8*4)+(7*1)+(6*6)+(5*4)+(4*4)+(3*2)+(2*3)+(1*4)=136
136 % 10 = 6
So 1416442-34-6 is a valid CAS Registry Number.

Design, synthesis and biological evaluation of new peptide-based ureas and thioureas as potential antagonists of the thrombin receptor PAR1

Ventosa-Andrés, Pilar,Valdivielso, ángel M.,Pappos, Ioannis,Teresa García-López,Tsopanoglou, Nikos E.,Herranz, Rosario

, p. 98 - 111 (2013/02/23)

By applying a diversity oriented synthesis strategy for the search of new antagonists of the thrombin receptor PAR1, a series of peptide-based ureas and thioureas, including analogues of the PAR1 reference antagonist RWJ-58259, has been designed and synthesized. The general synthetic scheme involves reduction of basic amino acid-derived amino nitriles by hydrogen transfer from hydrazine monohydrate in the presence of Raney Ni, followed by reaction with diverse isocyanates and isothiocyanates, and protecting group removal. All new compounds have been evaluated as inhibitors of human platelet aggregation induced by the PAR1 agonist SFLLRN. Some protected peptide-based ureas displayed significant antagonist activity.
