74148-98-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74148-98-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,1,4 and 8 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 74148-98:
(7*7)+(6*4)+(5*1)+(4*4)+(3*8)+(2*9)+(1*8)=144
144 % 10 = 4
So 74148-98-4 is a valid CAS Registry Number.
