53555-13-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 53555-13-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,3,5,5 and 5 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 53555-13:
(7*5)+(6*3)+(5*5)+(4*5)+(3*5)+(2*1)+(1*3)=118
118 % 10 = 8
So 53555-13-8 is a valid CAS Registry Number.
