497236-97-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 497236-97-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,9,7,2,3 and 6 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 497236-97:
(8*4)+(7*9)+(6*7)+(5*2)+(4*3)+(3*6)+(2*9)+(1*7)=202
202 % 10 = 2
So 497236-97-2 is a valid CAS Registry Number.
