499971-00-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 499971-00-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,9,9,9,7 and 1 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 499971-00:
(8*4)+(7*9)+(6*9)+(5*9)+(4*7)+(3*1)+(2*0)+(1*0)=225
225 % 10 = 5
So 499971-00-5 is a valid CAS Registry Number.
