13193-50-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 13193-50-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,1,9 and 3 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 13193-50:
(7*1)+(6*3)+(5*1)+(4*9)+(3*3)+(2*5)+(1*0)=85
85 % 10 = 5
So 13193-50-5 is a valid CAS Registry Number.
