499218-40-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 499218-40-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,9,9,2,1 and 8 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 499218-40:
(8*4)+(7*9)+(6*9)+(5*2)+(4*1)+(3*8)+(2*4)+(1*0)=195
195 % 10 = 5
So 499218-40-5 is a valid CAS Registry Number.
