497058-78-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 497058-78-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,9,7,0,5 and 8 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 497058-78:
(8*4)+(7*9)+(6*7)+(5*0)+(4*5)+(3*8)+(2*7)+(1*8)=203
203 % 10 = 3
So 497058-78-3 is a valid CAS Registry Number.
