109178-76-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 109178-76-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,1,7 and 8 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 109178-76:
(8*1)+(7*0)+(6*9)+(5*1)+(4*7)+(3*8)+(2*7)+(1*6)=139
139 % 10 = 9
So 109178-76-9 is a valid CAS Registry Number.
