19348-41-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 19348-41-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,3,4 and 8 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 19348-41:
(7*1)+(6*9)+(5*3)+(4*4)+(3*8)+(2*4)+(1*1)=125
125 % 10 = 5
So 19348-41-5 is a valid CAS Registry Number.
