Check Digit Verification of cas no
The CAS Registry Mumber 56140-50-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,6,1,4 and 0 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 56140-50:
(7*5)+(6*6)+(5*1)+(4*4)+(3*0)+(2*5)+(1*0)=102
102 % 10 = 2
So 56140-50-2 is a valid CAS Registry Number.
