188903-20-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 188903-20-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,8,9,0 and 3 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 188903-20:
(8*1)+(7*8)+(6*8)+(5*9)+(4*0)+(3*3)+(2*2)+(1*0)=170
170 % 10 = 0
So 188903-20-0 is a valid CAS Registry Number.
