Check Digit Verification of cas no
The CAS Registry Mumber 1898-13-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,8,9 and 8 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1898-13:
(6*1)+(5*8)+(4*9)+(3*8)+(2*1)+(1*3)=111
111 % 10 = 1
So 1898-13-1 is a valid CAS Registry Number.

Novel Synthesis of (-)-(R)-Cembrene A, Synthesis of (+)-(R)-Cembrenene and (+)-(S)-Cembrene
Farkas, Imre,Pfander, Hanspeter
, p. 1980 - 1985 (2007/10/02)
A novel synthesis of (-)-(R)-cembrene A ((-)-3) was developed using the Sharpless epoxidation for the introduction of the chiral center.Furthermore, the synthesis of (+)-(R)-cembrenene ((+)-4) showed that this cembranoid must have the (R)-configuration and not, as previously reported, the (S)-confguration.Selective hydrogebation of (+)-4 afforded (+)-(S)-cembrene ((+)-5).
