Check Digit Verification of cas no

The CAS Registry Mumber 410080-99-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,1,0,0,8 and 0 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 410080-99:
(8*4)+(7*1)+(6*0)+(5*0)+(4*8)+(3*0)+(2*9)+(1*9)=98
98 % 10 = 8
So 410080-99-8 is a valid CAS Registry Number.

Applications of crotyldiisopinocampheylboranes in synthesis: A formal total synthesis of (+)-calyculin A

Anderson, Oren P.,Barrett, Anthony G.M.,Edmunds, Jeremy J.,Hachiya, Shun-Ichiro,Hendrix, James A.,Horita, Kiyoshi,Malecha, James W.,Parkinson, Christopher J.,Vansickle, Andrew

, p. 1562 - 1592 (2007/10/03)

The formal total synthesis of the marine metabolite (+)-calyculin A is reported. The key steps involve (i) the use of Brown allylboration chemistry to control the relative and absolute stereochemistry of homoallylic alcohol arrays, thus setting eight of the desired stereocenters; (ii) Stille coupling methodology in the construction of the cyano tetraene unit of the natural product; and (iii) a modified Cornforth-Meyers approach to the synthesis of the oxazole fragment.
