Check Digit Verification of cas no
The CAS Registry Mumber 69938-56-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,9,3 and 8 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 69938-56:
(7*6)+(6*9)+(5*9)+(4*3)+(3*8)+(2*5)+(1*6)=193
193 % 10 = 3
So 69938-56-3 is a valid CAS Registry Number.
