Check Digit Verification of cas no
The CAS Registry Mumber 179927-72-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,9,9,2 and 7 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 179927-72:
(8*1)+(7*7)+(6*9)+(5*9)+(4*2)+(3*7)+(2*7)+(1*2)=201
201 % 10 = 1
So 179927-72-1 is a valid CAS Registry Number.

Hydroxyl-directed reductive ring opening at the C-2 position of functionalized 2-aryloxetanes
Bach, Thorsten,Lange, Christian
, p. 4363 - 4364 (2007/10/03)
2-Aryloxetanes 3 are cleaved at the C-2 position upon treatment with lithium aluminium hydride to deliver the triols 4 in good yields (61-85 %). The regioselective ring opening at the more hindered position is facilitated by a hydoxyl group attached to the arene.
