Check Digit Verification of cas no

The CAS Registry Mumber 1204501-06-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,4,5,0 and 1 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1204501-06:
(9*1)+(8*2)+(7*0)+(6*4)+(5*5)+(4*0)+(3*1)+(2*0)+(1*6)=83
83 % 10 = 3
So 1204501-06-3 is a valid CAS Registry Number.

Preparation of tethered aldehyde ynoates and ynones by ring fragmentation of cyclic γ-oxy-β-hydroxy-α-diazo carbonyls

Bayir, Ali,Draghici, Cristian,Brewer, Matthias

supporting information; experimental part, p. 296 - 302 (2010/03/30)

(Chemical Equation Presented) Cyclic γ-oxy-β-hydroxy-α- diazo carbonyls undergo Lewis acid induced ring fragmentation to provide either ynoates or ynones tethered to an aldehyde, ketone, or ester. The fragmentation precursors are convenient to prepare by adding lithiated α-diazo carbonyls to α-oxy ketones. The fragmentation appears general and provides a variety of functional group-rich products in good to excellent yield.
