Check Digit Verification of cas no

The CAS Registry Mumber 35508-99-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,5,5,0 and 8 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 35508-99:
(7*3)+(6*5)+(5*5)+(4*0)+(3*8)+(2*9)+(1*9)=127
127 % 10 = 7
So 35508-99-7 is a valid CAS Registry Number.

LiCl-promoted amination of β-methoxy amides (γ-lactones)

, p. 34938 - 34942 (2020/10/14)

An efficient and mild method has been developed for the amination of β-methoxy amides (γ-lactones) including natural products michelolide, costunolide and parthenolide derivatives by using lithium chloride in good yields. This reaction is applicable to a wide range of substrates with good functional group tolerance. Mechanism studies show that the reactions undergo a LiCl promoted MeOH elimination from the substrates to form the corresponding α,β-unsaturated intermediates followed by the Michael addition of amines.
