Check Digit Verification of cas no
The CAS Registry Mumber 444118-12-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,4,4,1,1 and 8 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 444118-12:
(8*4)+(7*4)+(6*4)+(5*1)+(4*1)+(3*8)+(2*1)+(1*2)=121
121 % 10 = 1
So 444118-12-1 is a valid CAS Registry Number.

Stereoselective approach to alk-2-yne-1,4-diols. Application to the synthesis of musclide B
Amador, Marta,Ariza, Xavier,Garcia, Jordi,Ortiz, Jordi
, p. 2691 - 2694 (2002)
An expedient method for the stereoselective preparation of alk-2-yne-1,4-diols has been achieved, based on the addition of chiral alk-1-yn-3-ols (or their protected derivatives) to aldehydes mediated by zinc triflate, Et3N, and (+)- or (-)-N-me
