Check Digit Verification of cas no
The CAS Registry Mumber 74185-47-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,1,8 and 5 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 74185-47:
(7*7)+(6*4)+(5*1)+(4*8)+(3*5)+(2*4)+(1*7)=140
140 % 10 = 0
So 74185-47-0 is a valid CAS Registry Number.
