Check Digit Verification of cas no
The CAS Registry Mumber 4857-81-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,8,5 and 7 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 4857-81:
(6*4)+(5*8)+(4*5)+(3*7)+(2*8)+(1*1)=122
122 % 10 = 2
So 4857-81-2 is a valid CAS Registry Number.
