849111-98-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 849111-98-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,4,9,1,1 and 1 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 849111-98:
(8*8)+(7*4)+(6*9)+(5*1)+(4*1)+(3*1)+(2*9)+(1*8)=184
184 % 10 = 4
So 849111-98-4 is a valid CAS Registry Number.
