104703-89-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 104703-89-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,7,0 and 3 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 104703-89:
(8*1)+(7*0)+(6*4)+(5*7)+(4*0)+(3*3)+(2*8)+(1*9)=101
101 % 10 = 1
So 104703-89-1 is a valid CAS Registry Number.
