Check Digit Verification of cas no
The CAS Registry Mumber 131340-09-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,3,4 and 0 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 131340-09:
(8*1)+(7*3)+(6*1)+(5*3)+(4*4)+(3*0)+(2*0)+(1*9)=75
75 % 10 = 5
So 131340-09-5 is a valid CAS Registry Number.
