656797-87-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 656797-87-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,5,6,7,9 and 7 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 656797-87:
(8*6)+(7*5)+(6*6)+(5*7)+(4*9)+(3*7)+(2*8)+(1*7)=234
234 % 10 = 4
So 656797-87-4 is a valid CAS Registry Number.
