130619-18-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 130619-18-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,6,1 and 9 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 130619-18:
(8*1)+(7*3)+(6*0)+(5*6)+(4*1)+(3*9)+(2*1)+(1*8)=100
100 % 10 = 0
So 130619-18-0 is a valid CAS Registry Number.
