13131-26-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 13131-26-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,1,3 and 1 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 13131-26:
(7*1)+(6*3)+(5*1)+(4*3)+(3*1)+(2*2)+(1*6)=55
55 % 10 = 5
So 13131-26-5 is a valid CAS Registry Number.
