17803-12-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 17803-12-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,8,0 and 3 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 17803-12:
(7*1)+(6*7)+(5*8)+(4*0)+(3*3)+(2*1)+(1*2)=102
102 % 10 = 2
So 17803-12-2 is a valid CAS Registry Number.
