74051-53-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74051-53-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,0,5 and 1 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 74051-53:
(7*7)+(6*4)+(5*0)+(4*5)+(3*1)+(2*5)+(1*3)=109
109 % 10 = 9
So 74051-53-9 is a valid CAS Registry Number.
