Check Digit Verification of cas no
The CAS Registry Mumber 69998-58-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,9,9 and 8 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 69998-58:
(7*6)+(6*9)+(5*9)+(4*9)+(3*8)+(2*5)+(1*8)=219
219 % 10 = 9
So 69998-58-9 is a valid CAS Registry Number.
