Check Digit Verification of cas no
The CAS Registry Mumber 1401606-57-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,0,1,6,0 and 6 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1401606-57:
(9*1)+(8*4)+(7*0)+(6*1)+(5*6)+(4*0)+(3*6)+(2*5)+(1*7)=112
112 % 10 = 2
So 1401606-57-2 is a valid CAS Registry Number.

Total synthesis of 7′,8′-dihydroaigialospirol
Yuen, Tsz-Ying,Brimble, Margaret A.
, p. 5154 - 5157 (2013/01/15)
A highly convergent total synthesis of 7′,8′- dihydroaigialospirol is described. Key steps of the synthesis include a Nozaki-Hiyama-Kishi (NHK) coupling of an iodoalkyne with an advanced phthalide-aldehyde and a remarkable one-pot acid-mediated global deprotection/spiroacetalization.
