The CAS Registry Mumber 129138-68-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,1,3 and 8 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 129138-68:
(8*1)+(7*2)+(6*9)+(5*1)+(4*3)+(3*8)+(2*6)+(1*8)=137
137 % 10 = 7
So 129138-68-7 is a valid CAS Registry Number.
