90090-38-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 90090-38-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,0,9 and 0 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 90090-38:
(7*9)+(6*0)+(5*0)+(4*9)+(3*0)+(2*3)+(1*8)=113
113 % 10 = 3
So 90090-38-3 is a valid CAS Registry Number.
