Check Digit Verification of cas no
The CAS Registry Mumber 78502-49-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,5,0 and 2 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 78502-49:
(7*7)+(6*8)+(5*5)+(4*0)+(3*2)+(2*4)+(1*9)=145
145 % 10 = 5
So 78502-49-5 is a valid CAS Registry Number.
