684283-72-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 684283-72-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,8,4,2,8 and 3 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 684283-72:
(8*6)+(7*8)+(6*4)+(5*2)+(4*8)+(3*3)+(2*7)+(1*2)=195
195 % 10 = 5
So 684283-72-5 is a valid CAS Registry Number.
