135330-80-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 135330-80-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,3,3 and 0 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 135330-80:
(8*1)+(7*3)+(6*5)+(5*3)+(4*3)+(3*0)+(2*8)+(1*0)=102
102 % 10 = 2
So 135330-80-2 is a valid CAS Registry Number.
