Check Digit Verification of cas no
The CAS Registry Mumber 78893-18-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,8,9 and 3 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 78893-18:
(7*7)+(6*8)+(5*8)+(4*9)+(3*3)+(2*1)+(1*8)=192
192 % 10 = 2
So 78893-18-2 is a valid CAS Registry Number.
