The CAS Registry Mumber 1280640-13-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,0,6,4 and 0 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1280640-13:
(9*1)+(8*2)+(7*8)+(6*0)+(5*6)+(4*4)+(3*0)+(2*1)+(1*3)=132
132 % 10 = 2
So 1280640-13-2 is a valid CAS Registry Number.
