The CAS Registry Mumber 30336-83-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,0,3,3 and 6 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 30336-83:
(7*3)+(6*0)+(5*3)+(4*3)+(3*6)+(2*8)+(1*3)=85
85 % 10 = 5
So 30336-83-5 is a valid CAS Registry Number.
