433222-68-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 433222-68-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,3,3,2,2 and 2 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 433222-68:
(8*4)+(7*3)+(6*3)+(5*2)+(4*2)+(3*2)+(2*6)+(1*8)=115
115 % 10 = 5
So 433222-68-5 is a valid CAS Registry Number.
