Check Digit Verification of cas no
The CAS Registry Mumber 138448-17-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,4,4 and 8 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 138448-17:
(8*1)+(7*3)+(6*8)+(5*4)+(4*4)+(3*8)+(2*1)+(1*7)=146
146 % 10 = 6
So 138448-17-6 is a valid CAS Registry Number.
