497924-31-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 497924-31-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,9,7,9,2 and 4 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 497924-31:
(8*4)+(7*9)+(6*7)+(5*9)+(4*2)+(3*4)+(2*3)+(1*1)=209
209 % 10 = 9
So 497924-31-9 is a valid CAS Registry Number.
