131193-65-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 131193-65-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,1,9 and 3 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 131193-65:
(8*1)+(7*3)+(6*1)+(5*1)+(4*9)+(3*3)+(2*6)+(1*5)=102
102 % 10 = 2
So 131193-65-2 is a valid CAS Registry Number.
