184877-31-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 184877-31-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,4,8,7 and 7 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 184877-31:
(8*1)+(7*8)+(6*4)+(5*8)+(4*7)+(3*7)+(2*3)+(1*1)=184
184 % 10 = 4
So 184877-31-4 is a valid CAS Registry Number.
