Check Digit Verification of cas no
The CAS Registry Mumber 75673-18-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,6,7 and 3 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 75673-18:
(7*7)+(6*5)+(5*6)+(4*7)+(3*3)+(2*1)+(1*8)=156
156 % 10 = 6
So 75673-18-6 is a valid CAS Registry Number.
