1171014-48-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1171014-48-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,7,1,0,1 and 4 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1171014-48:
(9*1)+(8*1)+(7*7)+(6*1)+(5*0)+(4*1)+(3*4)+(2*4)+(1*8)=104
104 % 10 = 4
So 1171014-48-4 is a valid CAS Registry Number.
