Check Digit Verification of cas no
The CAS Registry Mumber 1809-02-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,8,0 and 9 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1809-02:
(6*1)+(5*8)+(4*0)+(3*9)+(2*0)+(1*2)=75
75 % 10 = 5
So 1809-02-5 is a valid CAS Registry Number.
