Check Digit Verification of cas no
The CAS Registry Mumber 109002-07-5 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 2 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 109002-07:
(8*1)+(7*0)+(6*9)+(5*0)+(4*0)+(3*2)+(2*0)+(1*7)=75
75 % 10 = 5
So 109002-07-5 is a valid CAS Registry Number.
