Check Digit Verification of cas no
The CAS Registry Mumber 7584-33-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,5,8 and 4 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 7584-33:
(6*7)+(5*5)+(4*8)+(3*4)+(2*3)+(1*3)=120
120 % 10 = 0
So 7584-33-0 is a valid CAS Registry Number.
