Check Digit Verification of cas no
The CAS Registry Mumber 131880-56-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,8,8 and 0 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 131880-56:
(8*1)+(7*3)+(6*1)+(5*8)+(4*8)+(3*0)+(2*5)+(1*6)=123
123 % 10 = 3
So 131880-56-3 is a valid CAS Registry Number.
