Check Digit Verification of cas no
The CAS Registry Mumber 50925-42-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,0,9,2 and 5 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 50925-42:
(7*5)+(6*0)+(5*9)+(4*2)+(3*5)+(2*4)+(1*2)=113
113 % 10 = 3
So 50925-42-3 is a valid CAS Registry Number.
