1028181-31-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1028181-31-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,8,1,8 and 1 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1028181-31:
(9*1)+(8*0)+(7*2)+(6*8)+(5*1)+(4*8)+(3*1)+(2*3)+(1*1)=118
118 % 10 = 8
So 1028181-31-8 is a valid CAS Registry Number.
