130268-18-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 130268-18-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,2,6 and 8 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 130268-18:
(8*1)+(7*3)+(6*0)+(5*2)+(4*6)+(3*8)+(2*1)+(1*8)=97
97 % 10 = 7
So 130268-18-7 is a valid CAS Registry Number.
