780-99-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 780-99-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,8 and 0 respectively; the second part has 2 digits, 9 and 9 respectively.Calculate Digit Verification of CAS Registry Number 780-99:
(5*7)+(4*8)+(3*0)+(2*9)+(1*9)=94
94 % 10 = 4
So 780-99-4 is a valid CAS Registry Number.
