245543-97-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 245543-97-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,5,5,4 and 3 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 245543-97:
(8*2)+(7*4)+(6*5)+(5*5)+(4*4)+(3*3)+(2*9)+(1*7)=149
149 % 10 = 9
So 245543-97-9 is a valid CAS Registry Number.
