Check Digit Verification of cas no
The CAS Registry Mumber 173310-57-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,3,3,1 and 0 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 173310-57:
(8*1)+(7*7)+(6*3)+(5*3)+(4*1)+(3*0)+(2*5)+(1*7)=111
111 % 10 = 1
So 173310-57-1 is a valid CAS Registry Number.

Stereoselective synthesis of (±)-urechitol A employing [4+3] cycloaddition
Sumiya, Tatsunobu,Ishigami, Ken,Watanabe, Hidenori
, p. 6982 - 6987 (2016)
Urechitol A was synthesized as a racemate employing a [4+3] cycloaddition reaction and a methanol assisted intramolecular epoxide opening as key steps for efficient construction of the core tricyclic framework. The overall yield was 2.4% over 12 steps.
