Check Digit Verification of cas no
The CAS Registry Mumber 1104-78-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,0 and 4 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1104-78:
(6*1)+(5*1)+(4*0)+(3*4)+(2*7)+(1*8)=45
45 % 10 = 5
So 1104-78-5 is a valid CAS Registry Number.
