7682-09-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 7682-09-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,6,8 and 2 respectively; the second part has 2 digits, 0 and 9 respectively.Calculate Digit Verification of CAS Registry Number 7682-09:
(6*7)+(5*6)+(4*8)+(3*2)+(2*0)+(1*9)=119
119 % 10 = 9
So 7682-09-9 is a valid CAS Registry Number.
