499157-55-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 499157-55-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,9,9,1,5 and 7 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 499157-55:
(8*4)+(7*9)+(6*9)+(5*1)+(4*5)+(3*7)+(2*5)+(1*5)=210
210 % 10 = 0
So 499157-55-0 is a valid CAS Registry Number.
