873320-13-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 873320-13-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,3,3,2 and 0 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 873320-13:
(8*8)+(7*7)+(6*3)+(5*3)+(4*2)+(3*0)+(2*1)+(1*3)=159
159 % 10 = 9
So 873320-13-9 is a valid CAS Registry Number.
