780-57-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 780-57-4 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, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 780-57:
(5*7)+(4*8)+(3*0)+(2*5)+(1*7)=84
84 % 10 = 4
So 780-57-4 is a valid CAS Registry Number.
