Check Digit Verification of cas no
The CAS Registry Mumber 78133-80-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,1,3 and 3 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 78133-80:
(7*7)+(6*8)+(5*1)+(4*3)+(3*3)+(2*8)+(1*0)=139
139 % 10 = 9
So 78133-80-9 is a valid CAS Registry Number.
