The CAS Registry Mumber 1452831-72-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,5,2,8,3 and 1 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1452831-72:
(9*1)+(8*4)+(7*5)+(6*2)+(5*8)+(4*3)+(3*1)+(2*7)+(1*2)=159
159 % 10 = 9
So 1452831-72-9 is a valid CAS Registry Number.
