90255-55-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 90255-55-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,2,5 and 5 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 90255-55:
(7*9)+(6*0)+(5*2)+(4*5)+(3*5)+(2*5)+(1*5)=123
123 % 10 = 3
So 90255-55-3 is a valid CAS Registry Number.
