137022-75-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 137022-75-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,0,2 and 2 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 137022-75:
(8*1)+(7*3)+(6*7)+(5*0)+(4*2)+(3*2)+(2*7)+(1*5)=104
104 % 10 = 4
So 137022-75-4 is a valid CAS Registry Number.

, p. 1489 - 1494 (2007/10/02)
To develop a potent and specific collagenase inhibitor, a series of tetrapeptidyl hydroxamic acids were synthesized, based on the previous findings with tripeptidyl derivatives (Chem. Pharm. Bull., 38, 1007-1011, 1990). Among the series of tetrapeptidyl d
