Check Digit Verification of cas no
The CAS Registry Mumber 99549-42-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,5,4 and 9 respectively; the second part has 2 digits, 4 and 2 respectively.Calculate Digit Verification of CAS Registry Number 99549-42:
(7*9)+(6*9)+(5*5)+(4*4)+(3*9)+(2*4)+(1*2)=195
195 % 10 = 5
So 99549-42-5 is a valid CAS Registry Number.
