74222-03-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74222-03-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,2,2 and 2 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 74222-03:
(7*7)+(6*4)+(5*2)+(4*2)+(3*2)+(2*0)+(1*3)=100
100 % 10 = 0
So 74222-03-0 is a valid CAS Registry Number.
