Check Digit Verification of cas no

The CAS Registry Mumber 157736-55-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,7,3 and 6 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 157736-55:
(8*1)+(7*5)+(6*7)+(5*7)+(4*3)+(3*6)+(2*5)+(1*5)=165
165 % 10 = 5
So 157736-55-5 is a valid CAS Registry Number.

A NOVEL SYNTHESIS OF 3,3-(SPIRO)SUBSTITUTED AZETIDINES

Froehlich, Johannes,Sauter, Fritz,Blasl, Karin

, p. 1879 - 1892 (2007/10/02)

A smooth and efficient new synthesis for 3,3-disubstituted azetidines, starting from readily available nitriles, was estabilished: α-hydroxymethylation of the starting materials, followed by O-tosylation and LiAlH4-reduction of the key intermediates thus obtained, led - via spontaneous cyclization of the intermediate amino derivatives - to 3,3-disubstituted azetidines.Scope and limitations of this new method were studied with respect to generalized applicability: the target compounds were accessible in good yields for a variety of starting materials (cyclic and acyclic di(hetero)aryl, (hetero)arylalkyl, dialkyl, as well as basic moieties).The products thus obtained may be of interest for ensuing conversions due to their unblocked nitrogen.
