1305155-35-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1305155-35-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,0,5,1,5 and 5 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1305155-35:
(9*1)+(8*3)+(7*0)+(6*5)+(5*1)+(4*5)+(3*5)+(2*3)+(1*5)=114
114 % 10 = 4
So 1305155-35-4 is a valid CAS Registry Number.
