Check Digit Verification of cas no

The CAS Registry Mumber 121668-41-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,6,6 and 8 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 121668-41:
(8*1)+(7*2)+(6*1)+(5*6)+(4*6)+(3*8)+(2*4)+(1*1)=115
115 % 10 = 5
So 121668-41-5 is a valid CAS Registry Number.

RING OPENING OF 2,2,4,6,6-PENTACHLORO-4-FENYLDIMEDONE AFFORDING AN α,α-DICHLORO-γ-BUTYROLACTONE

Buyck, L. De,Pooter, H. De,Schamp, N.

, p. 793 - 794 (2007/10/02)

An α,α-Dichloro-γ-butyrolactone 4 was formed after ring opening of 2,2,4,6,6-pentachloro-4-fenyldimedone with NaOAc-HOAc in aqueous dioxane.The ring opening in methanol gave a δ-ketoester 5 which was cyclised with Na2CO3 to afford the cyclic enol ether 6.
