The CAS Registry Mumber 1964-81-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,9,6 and 4 respectively; the second part has 2 digits, 8 and 1 respectively. Calculate Digit Verification of CAS Registry Number 1964-81: (6*1)+(5*9)+(4*6)+(3*4)+(2*8)+(1*1)=104 104 % 10 = 4 So 1964-81-4 is a valid CAS Registry Number.
