117979-65-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 117979-65-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,9,7 and 9 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 117979-65:
(8*1)+(7*1)+(6*7)+(5*9)+(4*7)+(3*9)+(2*6)+(1*5)=174
174 % 10 = 4
So 117979-65-4 is a valid CAS Registry Number.
