161258-31-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 161258-31-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,1,2,5 and 8 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 161258-31:
(8*1)+(7*6)+(6*1)+(5*2)+(4*5)+(3*8)+(2*3)+(1*1)=117
117 % 10 = 7
So 161258-31-7 is a valid CAS Registry Number.

A NEW FLUOROGENIC SUBSTRATE OF CARBOXYPEPTIDASE H - o-COUMAROYLPHENYLALANYLALANYLARGININE
Pozdnev, V. F.,Varlamov, O. L.,Grigor'yants, O. O.,Gomazkov, O. A.
, p. 213 - 218 (2007/10/02)
A new fluorogenic substrate is proposed for determining the enzymatic activity of carboxypeptidase H - o-coumaryl-L-phenylalanyl-L-alanyl-L-arginine (Cum-Phe-Ala-Arg-OH).The enzymatic hydrolysis of the substrate forms Cum-Phe-Ala-OH, which is determined f
