The CAS Registry Mumber 1293503-44-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,9,3,5,0 and 3 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1293503-44:
(9*1)+(8*2)+(7*9)+(6*3)+(5*5)+(4*0)+(3*3)+(2*4)+(1*4)=152
152 % 10 = 2
So 1293503-44-2 is a valid CAS Registry Number.
