Check Digit Verification of cas no
The CAS Registry Mumber 288571-74-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,8,5,7 and 1 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 288571-74:
(8*2)+(7*8)+(6*8)+(5*5)+(4*7)+(3*1)+(2*7)+(1*4)=194
194 % 10 = 4
So 288571-74-4 is a valid CAS Registry Number.
