130208-91-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 130208-91-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,2,0 and 8 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 130208-91:
(8*1)+(7*3)+(6*0)+(5*2)+(4*0)+(3*8)+(2*9)+(1*1)=82
82 % 10 = 2
So 130208-91-2 is a valid CAS Registry Number.
