The CAS Registry Mumber 1263307-44-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,3,3,0 and 7 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1263307-44:
(9*1)+(8*2)+(7*6)+(6*3)+(5*3)+(4*0)+(3*7)+(2*4)+(1*4)=133
133 % 10 = 3
So 1263307-44-3 is a valid CAS Registry Number.
