74221-00-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74221-00-4 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 1 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 74221-00:
(7*7)+(6*4)+(5*2)+(4*2)+(3*1)+(2*0)+(1*0)=94
94 % 10 = 4
So 74221-00-4 is a valid CAS Registry Number.
