Check Digit Verification of cas no
The CAS Registry Mumber 64178-58-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,1,7 and 8 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 64178-58:
(7*6)+(6*4)+(5*1)+(4*7)+(3*8)+(2*5)+(1*8)=141
141 % 10 = 1
So 64178-58-1 is a valid CAS Registry Number.
