98049-45-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 98049-45-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,0,4 and 9 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 98049-45:
(7*9)+(6*8)+(5*0)+(4*4)+(3*9)+(2*4)+(1*5)=167
167 % 10 = 7
So 98049-45-7 is a valid CAS Registry Number.
