Check Digit Verification of cas no
The CAS Registry Mumber 176240-20-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,6,2,4 and 0 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 176240-20:
(8*1)+(7*7)+(6*6)+(5*2)+(4*4)+(3*0)+(2*2)+(1*0)=123
123 % 10 = 3
So 176240-20-3 is a valid CAS Registry Number.
