90594-22-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 90594-22-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,5,9 and 4 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 90594-22:
(7*9)+(6*0)+(5*5)+(4*9)+(3*4)+(2*2)+(1*2)=142
142 % 10 = 2
So 90594-22-2 is a valid CAS Registry Number.
