185681-41-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 185681-41-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,5,6,8 and 1 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 185681-41:
(8*1)+(7*8)+(6*5)+(5*6)+(4*8)+(3*1)+(2*4)+(1*1)=168
168 % 10 = 8
So 185681-41-8 is a valid CAS Registry Number.

A facile stereoselective synthesis of sphingosine and ceramide
Li, Yun-Long,Wu, Yu-Lin
, p. 2079 - 2082 (2007/10/03)
Flexible syntheses of sphingosine and ceramide were achieved by using D-xylose as the chiral pool and a CuCN-catalyzed allylic alkylation reaction of a dimesylate 8 for chain elongation with concomitant control of an E configuration of the double bond. VCH Verlagsgesellschaft mbH, 1996.
