Check Digit Verification of cas no
The CAS Registry Mumber 90330-20-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,3,3 and 0 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 90330-20:
(7*9)+(6*0)+(5*3)+(4*3)+(3*0)+(2*2)+(1*0)=94
94 % 10 = 4
So 90330-20-4 is a valid CAS Registry Number.
