130820-55-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 130820-55-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,8,2 and 0 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 130820-55:
(8*1)+(7*3)+(6*0)+(5*8)+(4*2)+(3*0)+(2*5)+(1*5)=92
92 % 10 = 2
So 130820-55-2 is a valid CAS Registry Number.
