130562-89-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 130562-89-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,5,6 and 2 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 130562-89:
(8*1)+(7*3)+(6*0)+(5*5)+(4*6)+(3*2)+(2*8)+(1*9)=109
109 % 10 = 9
So 130562-89-9 is a valid CAS Registry Number.
