130930-81-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 130930-81-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,9,3 and 0 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 130930-81:
(8*1)+(7*3)+(6*0)+(5*9)+(4*3)+(3*0)+(2*8)+(1*1)=103
103 % 10 = 3
So 130930-81-3 is a valid CAS Registry Number.
