1132766-40-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1132766-40-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,3,2,7,6 and 6 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1132766-40:
(9*1)+(8*1)+(7*3)+(6*2)+(5*7)+(4*6)+(3*6)+(2*4)+(1*0)=135
135 % 10 = 5
So 1132766-40-5 is a valid CAS Registry Number.
