Check Digit Verification of cas no
The CAS Registry Mumber 50743-32-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,0,7,4 and 3 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 50743-32:
(7*5)+(6*0)+(5*7)+(4*4)+(3*3)+(2*3)+(1*2)=103
103 % 10 = 3
So 50743-32-3 is a valid CAS Registry Number.
