780767-57-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 780767-57-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,8,0,7,6 and 7 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 780767-57:
(8*7)+(7*8)+(6*0)+(5*7)+(4*6)+(3*7)+(2*5)+(1*7)=209
209 % 10 = 9
So 780767-57-9 is a valid CAS Registry Number.
