74022-52-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74022-52-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,0,2 and 2 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 74022-52:
(7*7)+(6*4)+(5*0)+(4*2)+(3*2)+(2*5)+(1*2)=99
99 % 10 = 9
So 74022-52-9 is a valid CAS Registry Number.
