449187-33-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 449187-33-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,4,9,1,8 and 7 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 449187-33:
(8*4)+(7*4)+(6*9)+(5*1)+(4*8)+(3*7)+(2*3)+(1*3)=181
181 % 10 = 1
So 449187-33-1 is a valid CAS Registry Number.
