90243-85-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 90243-85-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,2,4 and 3 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 90243-85:
(7*9)+(6*0)+(5*2)+(4*4)+(3*3)+(2*8)+(1*5)=119
119 % 10 = 9
So 90243-85-9 is a valid CAS Registry Number.
