Check Digit Verification of cas no

The CAS Registry Mumber 273214-46-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,7,3,2,1 and 4 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 273214-46:
(8*2)+(7*7)+(6*3)+(5*2)+(4*1)+(3*4)+(2*4)+(1*6)=123
123 % 10 = 3
So 273214-46-3 is a valid CAS Registry Number.

A new method for the synthesis of α-thio aldehydes and alcohols from aldehydes with one-carbon elongation

Satoh, Tsuyoshi,Kubota, Ko-Ichi

, p. 2121 - 2124 (2007/10/03)

A two-step and high-yield method for the synthesis of α-thio aldehydes from aldehydes with one-carbon elongation is realized by using chloromethyl phenyl sulfoxide as a one-carbon homologating agent. The α-thio aldehydes are easily converted to desulfurized alcohols with Bu3SnH and AIBN in refluxing benzene in good yield. (C) 2000 Elsevier Science Ltd.
