Check Digit Verification of cas no
The CAS Registry Mumber 78523-80-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,5,2 and 3 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 78523-80:
(7*7)+(6*8)+(5*5)+(4*2)+(3*3)+(2*8)+(1*0)=155
155 % 10 = 5
So 78523-80-5 is a valid CAS Registry Number.
