Check Digit Verification of cas no
The CAS Registry Mumber 131531-79-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,5,3 and 1 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 131531-79:
(8*1)+(7*3)+(6*1)+(5*5)+(4*3)+(3*1)+(2*7)+(1*9)=98
98 % 10 = 8
So 131531-79-8 is a valid CAS Registry Number.
