Check Digit Verification of cas no
The CAS Registry Mumber 78108-40-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,1,0 and 8 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 78108-40:
(7*7)+(6*8)+(5*1)+(4*0)+(3*8)+(2*4)+(1*0)=134
134 % 10 = 4
So 78108-40-4 is a valid CAS Registry Number.
