Check Digit Verification of cas no

The CAS Registry Mumber 1093169-42-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,9,3,1,6 and 9 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1093169-42:
(9*1)+(8*0)+(7*9)+(6*3)+(5*1)+(4*6)+(3*9)+(2*4)+(1*2)=156
156 % 10 = 6
So 1093169-42-6 is a valid CAS Registry Number.

Synthesis and structure revision of tyroscherin, a growth inhibitor of IGF-1-dependent tumor cells

Katsuta, Ryo,Shibata, Chié,Ishigami, Ken,Watanabe, Hidenori,Kitahara, Takeshi

, p. 7042 - 7045 (2008)

Synthesis of the proposed structure of tyroscherin, a growth inhibitor of IGF-1-dependent cancer cells, was succeeded by one-pot Julia coupling. However, spectral data of the synthetic compound were not identical with those of natural tyroscherin. The stereochemistry of tyroscherin was revised to be 2S,3R,8R,10R by syntheses of stereoisomers.
