Check Digit Verification of cas no
The CAS Registry Mumber 5850-93-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,8,5 and 0 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 5850-93:
(6*5)+(5*8)+(4*5)+(3*0)+(2*9)+(1*3)=111
111 % 10 = 1
So 5850-93-1 is a valid CAS Registry Number.
