Check Digit Verification of cas no
The CAS Registry Mumber 130265-30-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,2,6 and 5 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 130265-30:
(8*1)+(7*3)+(6*0)+(5*2)+(4*6)+(3*5)+(2*3)+(1*0)=84
84 % 10 = 4
So 130265-30-4 is a valid CAS Registry Number.
