32013-63-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 32013-63-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,2,0,1 and 3 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 32013-63:
(7*3)+(6*2)+(5*0)+(4*1)+(3*3)+(2*6)+(1*3)=61
61 % 10 = 1
So 32013-63-1 is a valid CAS Registry Number.
