132640-90-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 132640-90-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,6,4 and 0 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 132640-90:
(8*1)+(7*3)+(6*2)+(5*6)+(4*4)+(3*0)+(2*9)+(1*0)=105
105 % 10 = 5
So 132640-90-5 is a valid CAS Registry Number.
