433305-22-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 433305-22-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,3,3,3,0 and 5 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 433305-22:
(8*4)+(7*3)+(6*3)+(5*3)+(4*0)+(3*5)+(2*2)+(1*2)=107
107 % 10 = 7
So 433305-22-7 is a valid CAS Registry Number.
