Check Digit Verification of cas no
The CAS Registry Mumber 865792-18-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,5,7,9 and 2 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 865792-18:
(8*8)+(7*6)+(6*5)+(5*7)+(4*9)+(3*2)+(2*1)+(1*8)=223
223 % 10 = 3
So 865792-18-3 is a valid CAS Registry Number.
