1139696-29-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1139696-29-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,3,9,6,9 and 6 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1139696-29:
(9*1)+(8*1)+(7*3)+(6*9)+(5*6)+(4*9)+(3*6)+(2*2)+(1*9)=189
189 % 10 = 9
So 1139696-29-9 is a valid CAS Registry Number.
