435-90-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 435-90-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,3 and 5 respectively; the second part has 2 digits, 9 and 0 respectively.Calculate Digit Verification of CAS Registry Number 435-90:
(5*4)+(4*3)+(3*5)+(2*9)+(1*0)=65
65 % 10 = 5
So 435-90-5 is a valid CAS Registry Number.
