498556-57-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 498556-57-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,9,8,5,5 and 6 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 498556-57:
(8*4)+(7*9)+(6*8)+(5*5)+(4*5)+(3*6)+(2*5)+(1*7)=223
223 % 10 = 3
So 498556-57-3 is a valid CAS Registry Number.
