132665-89-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 132665-89-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,6,6 and 5 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 132665-89:
(8*1)+(7*3)+(6*2)+(5*6)+(4*6)+(3*5)+(2*8)+(1*9)=135
135 % 10 = 5
So 132665-89-5 is a valid CAS Registry Number.
