33066-22-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 33066-22-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,0,6 and 6 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 33066-22:
(7*3)+(6*3)+(5*0)+(4*6)+(3*6)+(2*2)+(1*2)=87
87 % 10 = 7
So 33066-22-7 is a valid CAS Registry Number.
