Check Digit Verification of cas no

The CAS Registry Mumber 84391-91-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,3,9 and 1 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 84391-91:
(7*8)+(6*4)+(5*3)+(4*9)+(3*1)+(2*9)+(1*1)=153
153 % 10 = 3
So 84391-91-3 is a valid CAS Registry Number.

Kamat,, Vinayak S.,Graden, David W.,Lynn, David G.,Steffens, John C.,Riopel, James L.

, p. 1541 - 1544 (1982)

Xenognosin, 4, the first identified host recognition substance for parasitic angiosperms has been synthesized by a route efficient for the preparation of several structural analoques.

Deoxygenation of α,β-unsaturated acylphenols through ethyl o-acylphenylcarbonates with Luche reduction

Yuan, Hu,Chen, Hao,Jin, Huizi,Li, Bo,Yue, Rongcai,Ye, Ji,Shen, Yunheng,Shan, Lei,Sun, Qingyan,Zhang, Weidong

, p. 2776 - 2780 (2013/06/05)

An efficient protocol for deoxygenation of α,β-unsaturated acylphenols through ethyl o-acylphenylcarbonates with Luche reduction is described. The reaction shows very good selectivity and tolerates a wide range of functionalities on α,β-unsaturated acylphenols, giving corresponding 2-allylphenols in good to excellent yields.
