Check Digit Verification of cas no
The CAS Registry Mumber 7608-18-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,6,0 and 8 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 7608-18:
(6*7)+(5*6)+(4*0)+(3*8)+(2*1)+(1*8)=106
106 % 10 = 6
So 7608-18-6 is a valid CAS Registry Number.
