Check Digit Verification of cas no
The CAS Registry Mumber 28767-74-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,7,6 and 7 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 28767-74:
(7*2)+(6*8)+(5*7)+(4*6)+(3*7)+(2*7)+(1*4)=160
160 % 10 = 0
So 28767-74-0 is a valid CAS Registry Number.
