133844-57-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 133844-57-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,8,4 and 4 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 133844-57:
(8*1)+(7*3)+(6*3)+(5*8)+(4*4)+(3*4)+(2*5)+(1*7)=132
132 % 10 = 2
So 133844-57-2 is a valid CAS Registry Number.

SILAKETALS AS TETHERS IN INTRAMOLECULAR RADICAL CYCLISATIONS
Hutchinson, John H.,Daynard, Tim S.,Gillard, John W.
, p. 573 - 576 (2007/10/02)
Intramolecular radical cyclisation reactions of substrates possessing a silaketal tether proceed predominantly via an endo mode in moderate to good yield to give 7, 8 or 9 membered ring products.The products, which are protected diols, can then be deprote
