7578-68-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 7578-68-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,5,7 and 8 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 7578-68:
(6*7)+(5*5)+(4*7)+(3*8)+(2*6)+(1*8)=139
139 % 10 = 9
So 7578-68-9 is a valid CAS Registry Number.
