Check Digit Verification of cas no
The CAS Registry Mumber 51768-87-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,7,6 and 8 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 51768-87:
(7*5)+(6*1)+(5*7)+(4*6)+(3*8)+(2*8)+(1*7)=147
147 % 10 = 7
So 51768-87-7 is a valid CAS Registry Number.
