449727-87-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 449727-87-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,4,9,7,2 and 7 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 449727-87:
(8*4)+(7*4)+(6*9)+(5*7)+(4*2)+(3*7)+(2*8)+(1*7)=201
201 % 10 = 1
So 449727-87-1 is a valid CAS Registry Number.
