Check Digit Verification of cas no
The CAS Registry Mumber 209865-54-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,9,8,6 and 5 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 209865-54:
(8*2)+(7*0)+(6*9)+(5*8)+(4*6)+(3*5)+(2*5)+(1*4)=163
163 % 10 = 3
So 209865-54-3 is a valid CAS Registry Number.
