Check Digit Verification of cas no
The CAS Registry Mumber 104142-18-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,1,4 and 2 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 104142-18:
(8*1)+(7*0)+(6*4)+(5*1)+(4*4)+(3*2)+(2*1)+(1*8)=69
69 % 10 = 9
So 104142-18-9 is a valid CAS Registry Number.
