81319-48-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 81319-48-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,3,1 and 9 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 81319-48:
(7*8)+(6*1)+(5*3)+(4*1)+(3*9)+(2*4)+(1*8)=124
124 % 10 = 4
So 81319-48-4 is a valid CAS Registry Number.

Tetrocarcin A was recently identified as an inhibitor of the anti-apoptotic function of Bcl-2. We synthesized novel tetrocarcin derivatives in order to increase their selective inhibitory activity against Bcl-2. It was found that 21-acetoxy-9-glycosyloxy derivatives had potent Bcl-2 inhibitory activity without significant antimicrobial activity.
