19432-41-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 19432-41-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,4,3 and 2 respectively; the second part has 2 digits, 4 and 1 respectively.Calculate Digit Verification of CAS Registry Number 19432-41:
(7*1)+(6*9)+(5*4)+(4*3)+(3*2)+(2*4)+(1*1)=108
108 % 10 = 8
So 19432-41-8 is a valid CAS Registry Number.
