Check Digit Verification of cas no
The CAS Registry Mumber 56969-22-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,6,9,6 and 9 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 56969-22:
(7*5)+(6*6)+(5*9)+(4*6)+(3*9)+(2*2)+(1*2)=173
173 % 10 = 3
So 56969-22-3 is a valid CAS Registry Number.
