Check Digit Verification of cas no
The CAS Registry Mumber 78807-87-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,8,0 and 7 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 78807-87:
(7*7)+(6*8)+(5*8)+(4*0)+(3*7)+(2*8)+(1*7)=181
181 % 10 = 1
So 78807-87-1 is a valid CAS Registry Number.
