The CAS Registry Mumber 1262841-07-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,2,8,4 and 1 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1262841-07:
(9*1)+(8*2)+(7*6)+(6*2)+(5*8)+(4*4)+(3*1)+(2*0)+(1*7)=145
145 % 10 = 5
So 1262841-07-5 is a valid CAS Registry Number.
