90254-41-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 90254-41-4 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 4 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 90254-41:
(7*9)+(6*0)+(5*2)+(4*5)+(3*4)+(2*4)+(1*1)=114
114 % 10 = 4
So 90254-41-4 is a valid CAS Registry Number.
