Check Digit Verification of cas no
The CAS Registry Mumber 143105-07-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,1,0 and 5 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 143105-07:
(8*1)+(7*4)+(6*3)+(5*1)+(4*0)+(3*5)+(2*0)+(1*7)=81
81 % 10 = 1
So 143105-07-1 is a valid CAS Registry Number.
