117340-77-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 117340-77-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,3,4 and 0 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 117340-77:
(8*1)+(7*1)+(6*7)+(5*3)+(4*4)+(3*0)+(2*7)+(1*7)=109
109 % 10 = 9
So 117340-77-9 is a valid CAS Registry Number.
