Check Digit Verification of cas no
The CAS Registry Mumber 109013-07-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,0,1 and 3 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 109013-07:
(8*1)+(7*0)+(6*9)+(5*0)+(4*1)+(3*3)+(2*0)+(1*7)=82
82 % 10 = 2
So 109013-07-2 is a valid CAS Registry Number.
