Check Digit Verification of cas no

The CAS Registry Mumber 570421-75-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,7,0,4,2 and 1 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 570421-75:
(8*5)+(7*7)+(6*0)+(5*4)+(4*2)+(3*1)+(2*7)+(1*5)=139
139 % 10 = 9
So 570421-75-9 is a valid CAS Registry Number.

The tert-butyl moiety - A base resistent thiol protecting group smoothly replaced by the labile acetyl moiety

Stuhr-Hansen, Nicolai

, p. 641 - 646 (2003)

Aryl t-butyl sulfides underwent quantitative tert-butyl/acetyl exchange reactions affording thioacetic acid S-aryl esters when treated with acetyl chloride and boron tribromide.

Utilization of microwave heating in the McMurry reaction for facile coupling of aldehydes and ketones to give alkenes

Stuhr-Hansen, Nicolai

, p. 5491 - 5494 (2007/10/03)

Microwave heating was applied in high-yield syntheses of alkenes by McMurry coupling of aldehydes and ketones with low-valent titanium. All aldehydes and ketones including sulfur end-capped analogues gave alkenes in isolated yields above 80% without detectable amounts of pinacols.
