90408-84-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 90408-84-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,4,0 and 8 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 90408-84:
(7*9)+(6*0)+(5*4)+(4*0)+(3*8)+(2*8)+(1*4)=127
127 % 10 = 7
So 90408-84-7 is a valid CAS Registry Number.
