Check Digit Verification of cas no
The CAS Registry Mumber 18945-81-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,9,4 and 5 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 18945-81:
(7*1)+(6*8)+(5*9)+(4*4)+(3*5)+(2*8)+(1*1)=148
148 % 10 = 8
So 18945-81-8 is a valid CAS Registry Number.

A number of novel difunctionalized furans and thiophenes has been prepared by the reaction of the cyano-substituted substrates with TMPMgCl·LiCl followed by the reaction with electrophiles. The crucial metalation step takes place under mild conditions allowing the isolation of desired derivatives in reasonable to good yields.
