140183-68-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 140183-68-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,1,8 and 3 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 140183-68:
(8*1)+(7*4)+(6*0)+(5*1)+(4*8)+(3*3)+(2*6)+(1*8)=102
102 % 10 = 2
So 140183-68-2 is a valid CAS Registry Number.

Studies of the synthesis of biomarkers. XI. Synthesis of 4,5-secocholestane and 4-methyl-4,5-secocholestane

Ma, Jian-Guo,Li, Tong-Shuang,Li, Yu-Lin

, p. 551 - 553 (1992)

4,5-Secocholestane (1a) and 4-methyl-4,5-secocholestane (1b) were synthesized from cholesterol (2) in five and seven steps, respectively. The key intermediate, 5-oxo-4,5-secocholestan-4-al (7) was reduced by the Clemmensen method to afford 1a. Meanwhile, 7 underwent selective Wittig reaction, Clemmensen reduction, and hydrogenation to give another target molecule, 1b. The structure of an unknown biomarker was shown to be different from the proposed la by gas Chromatographic and mass spectrometric comparison.
