Check Digit Verification of cas no
The CAS Registry Mumber 65938-77-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,5,9,3 and 8 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 65938-77:
(7*6)+(6*5)+(5*9)+(4*3)+(3*8)+(2*7)+(1*7)=174
174 % 10 = 4
So 65938-77-4 is a valid CAS Registry Number.
