1089731-11-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1089731-11-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,8,9,7,3 and 1 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1089731-11:
(9*1)+(8*0)+(7*8)+(6*9)+(5*7)+(4*3)+(3*1)+(2*1)+(1*1)=172
172 % 10 = 2
So 1089731-11-2 is a valid CAS Registry Number.
