Check Digit Verification of cas no
The CAS Registry Mumber 131497-72-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,4,9 and 7 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 131497-72:
(8*1)+(7*3)+(6*1)+(5*4)+(4*9)+(3*7)+(2*7)+(1*2)=128
128 % 10 = 8
So 131497-72-8 is a valid CAS Registry Number.
