117049-12-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 117049-12-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,0,4 and 9 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 117049-12:
(8*1)+(7*1)+(6*7)+(5*0)+(4*4)+(3*9)+(2*1)+(1*2)=104
104 % 10 = 4
So 117049-12-4 is a valid CAS Registry Number.
