188065-31-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 188065-31-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,8,0,6 and 5 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 188065-31:
(8*1)+(7*8)+(6*8)+(5*0)+(4*6)+(3*5)+(2*3)+(1*1)=158
158 % 10 = 8
So 188065-31-8 is a valid CAS Registry Number.
