Check Digit Verification of cas no
The CAS Registry Mumber 99239-19-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,2,3 and 9 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 99239-19:
(7*9)+(6*9)+(5*2)+(4*3)+(3*9)+(2*1)+(1*9)=177
177 % 10 = 7
So 99239-19-7 is a valid CAS Registry Number.
