685530-39-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 685530-39-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,8,5,5,3 and 0 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 685530-39:
(8*6)+(7*8)+(6*5)+(5*5)+(4*3)+(3*0)+(2*3)+(1*9)=186
186 % 10 = 6
So 685530-39-6 is a valid CAS Registry Number.
