Check Digit Verification of cas no
The CAS Registry Mumber 19349-78-1 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 9 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 19349-78:
(7*1)+(6*9)+(5*3)+(4*4)+(3*9)+(2*7)+(1*8)=141
141 % 10 = 1
So 19349-78-1 is a valid CAS Registry Number.
