121153-31-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 121153-31-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,1,5 and 3 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 121153-31:
(8*1)+(7*2)+(6*1)+(5*1)+(4*5)+(3*3)+(2*3)+(1*1)=69
69 % 10 = 9
So 121153-31-9 is a valid CAS Registry Number.

Synthesis of dithioacetals and oxathioacetals with chiral auxiliaries

Zaidi, Javid H.,Naeem, Fazal,Khan, Khalid M.,Iqbal, Rasfaid,Zia-Ullah

, p. 2641 - 2653 (2007/10/03)

One-pot synthesis of dithioacetals as well as an efficient method for oxathioacetal is reported. Additionally, some chiral auxiliaries were used to synthesize enantiomerically pure dithioacetals and oxathioacetals.

ACTIVATION AND SYNTHETIC APPLICATIONS OF THIOSTANNANES. THIOALKOXYLATION OF ACETALS

Sato, Tsuneo,Otera, Junzo,Nozaki, Hitosi

, p. 1209 - 1218 (2007/10/02)

The Sn-S bonds in thiostannanes, BunSn(SPh)4-n, are activated towards acetals in the presence of BF3*OEt2.Acetals of various aldehydes and ketones are converted into the corresponding monothioacetals under mild conditions.Employment of α-enal acetals induces Michael addition to give synthetically useful γ-alkoxyally sulfides.
