Check Digit Verification of cas no
The CAS Registry Mumber 19814-75-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,8,1 and 4 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 19814-75:
(7*1)+(6*9)+(5*8)+(4*1)+(3*4)+(2*7)+(1*5)=136
136 % 10 = 6
So 19814-75-6 is a valid CAS Registry Number.
