90504-37-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 90504-37-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,5,0 and 4 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 90504-37:
(7*9)+(6*0)+(5*5)+(4*0)+(3*4)+(2*3)+(1*7)=113
113 % 10 = 3
So 90504-37-3 is a valid CAS Registry Number.
