Check Digit Verification of cas no

The CAS Registry Mumber 1039740-38-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,3,9,7,4 and 0 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1039740-38:
(9*1)+(8*0)+(7*3)+(6*9)+(5*7)+(4*4)+(3*0)+(2*3)+(1*8)=149
149 % 10 = 9
So 1039740-38-9 is a valid CAS Registry Number.

Highly efficient stereocontrolled synthesis of danishefsky's taxol CD ring key intermediate

Bremond, Paul,Audran, Gerard,Monti, Honore

, p. 6033 - 6036 (2008/12/21)

(Chemical Equation Presented) Danishefsky's taxol CD ring key intermediate is synthesized in 15 steps and 11.4% overall yield from a readily available starting material. Absolute stereochemistry of the starting material and stereocontrolled steps determine the absolute configuration of the five requisite contiguous stereocenters.
