Check Digit Verification of cas no
The CAS Registry Mumber 42497-69-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,4,9 and 7 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 42497-69:
(7*4)+(6*2)+(5*4)+(4*9)+(3*7)+(2*6)+(1*9)=138
138 % 10 = 8
So 42497-69-8 is a valid CAS Registry Number.
