Check Digit Verification of cas no

The CAS Registry Mumber 144202-83-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,2,0 and 2 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 144202-83:
(8*1)+(7*4)+(6*4)+(5*2)+(4*0)+(3*2)+(2*8)+(1*3)=95
95 % 10 = 5
So 144202-83-5 is a valid CAS Registry Number.

Preferential Formation of Amino Acid Esters in Aqueous Alcohol Solutions: Solvolysis of 6,6'-Bis(aminoacylamino)-2,2'-bipyridine by Metal Coordination

Araki, Koji,Kuboki, Takashi,Yamada, Masaki,Shiraishi, Shinsaku

, p. 1060 - 1062 (1992)

Exclusive formation of amino acid esters took place at an appreciable rate in the CuII-catalysed solvolysis of 6,6'-(α-alanylamino or α-phenylalanylamino)-2,2'-bipyridine in alcohol-borate buffer (pH 7.2) solutions at 20 deg C via formation of an amide-O-coordinated complex, even though appreciable amounts of water (0-40percent v/v) were present in the solution.
