Check Digit Verification of cas no
The CAS Registry Mumber 67448-13-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,4,4 and 8 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 67448-13:
(7*6)+(6*7)+(5*4)+(4*4)+(3*8)+(2*1)+(1*3)=149
149 % 10 = 9
So 67448-13-9 is a valid CAS Registry Number.
