Check Digit Verification of cas no
The CAS Registry Mumber 18145-74-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,1,4 and 5 respectively; the second part has 2 digits, 7 and 4 respectively.Calculate Digit Verification of CAS Registry Number 18145-74:
(7*1)+(6*8)+(5*1)+(4*4)+(3*5)+(2*7)+(1*4)=109
109 % 10 = 9
So 18145-74-9 is a valid CAS Registry Number.
