720684-69-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 720684-69-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,2,0,6,8 and 4 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 720684-69:
(8*7)+(7*2)+(6*0)+(5*6)+(4*8)+(3*4)+(2*6)+(1*9)=165
165 % 10 = 5
So 720684-69-5 is a valid CAS Registry Number.
