Check Digit Verification of cas no

The CAS Registry Mumber 148149-83-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,8,1,4 and 9 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 148149-83:
(8*1)+(7*4)+(6*8)+(5*1)+(4*4)+(3*9)+(2*8)+(1*3)=151
151 % 10 = 1
So 148149-83-1 is a valid CAS Registry Number.

Asymmetric Total Synthesis of Pseudoplexaurol and 14-Deoxycrassin, two Antitumor Marine Cembrane Diterpenoids

Liu, Zuosheng,Peng, Lizeng,Li, Weidong Z.,Li, Yulin

, p. 1977 - 1980 (2007/10/03)

The first asymmetric total synthesis of two naturally occurring antitumor pseudoplexaurol and 14-deoxycrassin were achieved via two convergent synthetic sequences featured a chiral pool protocol to implement C-1 stereogenic center and Ti(0)-mediated cyclization leading to cembrane ring.
