Check Digit Verification of cas no
The CAS Registry Mumber 313973-99-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,1,3,9,7 and 3 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 313973-99:
(8*3)+(7*1)+(6*3)+(5*9)+(4*7)+(3*3)+(2*9)+(1*9)=158
158 % 10 = 8
So 313973-99-8 is a valid CAS Registry Number.
