669003-63-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 669003-63-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,6,9,0,0 and 3 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 669003-63:
(8*6)+(7*6)+(6*9)+(5*0)+(4*0)+(3*3)+(2*6)+(1*3)=168
168 % 10 = 8
So 669003-63-8 is a valid CAS Registry Number.

, p. 5833 - 5836 (2007/10/03)
Starting from the high-throughput screening hit 1a, novel cathepsin K inhibitors have been developed based on a purine scaffold. High-resolution X-ray structures of several derivatives have revealed the binding mode of these unique cysteine protease inhib
