1268809-85-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1268809-85-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,8,8,0 and 9 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1268809-85:
(9*1)+(8*2)+(7*6)+(6*8)+(5*8)+(4*0)+(3*9)+(2*8)+(1*5)=203
203 % 10 = 3
So 1268809-85-3 is a valid CAS Registry Number.
