13052-25-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 13052-25-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,0,5 and 2 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 13052-25:
(7*1)+(6*3)+(5*0)+(4*5)+(3*2)+(2*2)+(1*5)=60
60 % 10 = 0
