Check Digit Verification of cas no

The CAS Registry Mumber 640285-92-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,4,0,2,8 and 5 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 640285-92:
(8*6)+(7*4)+(6*0)+(5*2)+(4*8)+(3*5)+(2*9)+(1*2)=153
153 % 10 = 3
So 640285-92-3 is a valid CAS Registry Number.

(Chemical Equation Presented) 4-Alkoxy-2,2′-bipyrroles and the first examples of 4-amino-2,2′-bipyrroles have been synthesized by a diversity-oriented strategy from 4-hydroxyproline. The bipyrrole products offer interesting potential as building blocks fo

One-Pot Synthesis of Homoallylic Ketones from the Addition of Vinyl Grignard Reagent to Carboxylic Esters

Hansford, Karl A.,Dettwiler, James E.,Lubell, William D.

, p. 4887 - 4890 (2007/10/03)

(Equation Presented) Fifteen homoallylic ketones have been synthesized in 26-77% yields on treatment of aromatic, aliphatic, and α-amino methyl carboxylates with excess vinylmagnesium bromide and catalytic amounts of a copper salt in THF. α-Amino homoallylic ketones derived from N-protected α-amino esters possessing aliphatic and alcohol side chains were synthesized in ≥98% enantiomeric purity.
