The CAS Registry Mumber 1443121-01-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,3,1,2 and 1 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1443121-01:
(9*1)+(8*4)+(7*4)+(6*3)+(5*1)+(4*2)+(3*1)+(2*0)+(1*1)=104
104 % 10 = 4
So 1443121-01-4 is a valid CAS Registry Number.
