Check Digit Verification of cas no

The CAS Registry Mumber 132916-75-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,9,1 and 6 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 132916-75:
(8*1)+(7*3)+(6*2)+(5*9)+(4*1)+(3*6)+(2*7)+(1*5)=127
127 % 10 = 7
So 132916-75-7 is a valid CAS Registry Number.

Studies on lead tetraacetate oxidation of α-oxoketene dithioacetals

Bhat, Laxminarayan,Thomas, Abraham,Ila, Hiriyakkanavar,Junjappa, Hiriyakkanavar

, p. 305 - 312 (2007/10/19)

Lead Tetraacetate oxidation of acyclic α-acylketene dithioacetals 1 in refluxing benzene affords α-acetoxyketene dithioacetals 2 as major products which could be hydrolyzed to α-diketone dithioacetals 4 under mild alkaline conditions. Under similar oxidative conditions, α-cinnamoyl ketene dithioacetals 8 yield 2-acetoxycyclopentenone derivatives 9 through an interesting oxidative Nazarov cyclization involving intermediate α-acetoxy dithioacetals accompanied with 1,2-acyl group migration.
