The CAS Registry Mumber 3731-81-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,7,3 and 1 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 3731-81:
(6*3)+(5*7)+(4*3)+(3*1)+(2*8)+(1*1)=85
85 % 10 = 5
So 3731-81-5 is a valid CAS Registry Number.
