Check Digit Verification of cas no
The CAS Registry Mumber 18909-68-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,9,0 and 9 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 18909-68:
(7*1)+(6*8)+(5*9)+(4*0)+(3*9)+(2*6)+(1*8)=147
147 % 10 = 7
So 18909-68-7 is a valid CAS Registry Number.
