90503-20-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 90503-20-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,5,0 and 3 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 90503-20:
(7*9)+(6*0)+(5*5)+(4*0)+(3*3)+(2*2)+(1*0)=101
101 % 10 = 1
So 90503-20-1 is a valid CAS Registry Number.
