Check Digit Verification of cas no
The CAS Registry Mumber 61305-30-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,1,3,0 and 5 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 61305-30:
(7*6)+(6*1)+(5*3)+(4*0)+(3*5)+(2*3)+(1*0)=84
84 % 10 = 4
So 61305-30-4 is a valid CAS Registry Number.
