Check Digit Verification of cas no

The CAS Registry Mumber 126892-20-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,6,8,9 and 2 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 126892-20:
(8*1)+(7*2)+(6*6)+(5*8)+(4*9)+(3*2)+(2*2)+(1*0)=144
144 % 10 = 4
So 126892-20-4 is a valid CAS Registry Number.

Regio- and stereoselective functionalizations of the Wieland-Miescher ketone derivatives at the C-8 position

Shimizu, Takeshi,Hiranuma, Sayoko,Yoshioka, Hirosuke

, p. 1963 - 1965 (2007/10/02)

New efficient methods for stereoselective hydroxymethylation, hydroxylation, and thiophenylation at the C-8 position of the Wieland-Miescher ketone derivatives (2-4) have been developed by diverse modifications from the Kirk-Petrow reaction, which involve autoxidation for the hydroxylation.Keywords - Wieland-Miescher ketone; Kirk-Petrow reaction; phenylthio-methylation; hydroxylation; hydroxymethylation; thiophenylation.
