90415-73-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 90415-73-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,4,1 and 5 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 90415-73:
(7*9)+(6*0)+(5*4)+(4*1)+(3*5)+(2*7)+(1*3)=119
119 % 10 = 9
So 90415-73-9 is a valid CAS Registry Number.
