Check Digit Verification of cas no
The CAS Registry Mumber 131351-80-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,3,5 and 1 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 131351-80:
(8*1)+(7*3)+(6*1)+(5*3)+(4*5)+(3*1)+(2*8)+(1*0)=89
89 % 10 = 9
So 131351-80-9 is a valid CAS Registry Number.
