Check Digit Verification of cas no

The CAS Registry Mumber 1399843-67-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,9,9,8,4 and 3 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1399843-67:
(9*1)+(8*3)+(7*9)+(6*9)+(5*8)+(4*4)+(3*3)+(2*6)+(1*7)=234
234 % 10 = 4
So 1399843-67-4 is a valid CAS Registry Number.

Novel oxysterols activate the Hedgehog pathway and induce osteogenesis

Stappenbeck, Frank,Xiao, Wei,Epperson, Matt,Riley, Mariko,Priest, Aaron,Huang, Danwen,Scott Thies, R.,Farouz, Francine,Nguyen, Khanhlinh,Jung, Michael E.

, p. 5893 - 5897,5 (2020/07/31)

Localized induction of bone formation is essential during orthopedic procedures that involve skeletal repair, such as surgical treatment of non-union bone fractures and degenerative disk disease. Herein we disclose the synthesis and biological evaluation of novel oxysterol derivatives designed as anabolic bone growth agents. Structure-activity relationship studies of oxysterol 4 have identified analogues such as 18, 21 and 30. These new analogues are characterized by higher potency in an osteoblast differentiation assay and/or by increased metabolic stability in human liver microsomes. Oxysterols 4, 18 and 21 were evaluated in vivo in a rat spinal fusion model.
