53249-98-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 53249-98-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,3,2,4 and 9 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 53249-98:
(7*5)+(6*3)+(5*2)+(4*4)+(3*9)+(2*9)+(1*8)=132
132 % 10 = 2
So 53249-98-2 is a valid CAS Registry Number.
