Check Digit Verification of cas no
The CAS Registry Mumber 25667-42-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,6,6 and 7 respectively; the second part has 2 digits, 4 and 2 respectively.Calculate Digit Verification of CAS Registry Number 25667-42:
(7*2)+(6*5)+(5*6)+(4*6)+(3*7)+(2*4)+(1*2)=129
129 % 10 = 9
So 25667-42-9 is a valid CAS Registry Number.
