The CAS Registry Mumber 32831-41-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,2,8,3 and 1 respectively; the second part has 2 digits, 4 and 1 respectively. Calculate Digit Verification of CAS Registry Number 32831-41: (7*3)+(6*2)+(5*8)+(4*3)+(3*1)+(2*4)+(1*1)=97 97 % 10 = 7 So 32831-41-7 is a valid CAS Registry Number.
