66322-69-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 66322-69-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,3,2 and 2 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 66322-69:
(7*6)+(6*6)+(5*3)+(4*2)+(3*2)+(2*6)+(1*9)=128
128 % 10 = 8
So 66322-69-8 is a valid CAS Registry Number.
