130823-52-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 130823-52-8 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 3 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 130823-52:
(8*1)+(7*3)+(6*0)+(5*8)+(4*2)+(3*3)+(2*5)+(1*2)=98
98 % 10 = 8
So 130823-52-8 is a valid CAS Registry Number.
