130752-21-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 130752-21-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,7,5 and 2 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 130752-21:
(8*1)+(7*3)+(6*0)+(5*7)+(4*5)+(3*2)+(2*2)+(1*1)=95
95 % 10 = 5
So 130752-21-5 is a valid CAS Registry Number.
