The CAS Registry Mumber 109005-00-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,0,0 and 5 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 109005-00:
(8*1)+(7*0)+(6*9)+(5*0)+(4*0)+(3*5)+(2*0)+(1*0)=77
77 % 10 = 7
So 109005-00-7 is a valid CAS Registry Number.
