499195-38-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 499195-38-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,9,9,1,9 and 5 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 499195-38:
(8*4)+(7*9)+(6*9)+(5*1)+(4*9)+(3*5)+(2*3)+(1*8)=219
219 % 10 = 9
So 499195-38-9 is a valid CAS Registry Number.
