Check Digit Verification of cas no

The CAS Registry Mumber 137469-55-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,4,6 and 9 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 137469-55:
(8*1)+(7*3)+(6*7)+(5*4)+(4*6)+(3*9)+(2*5)+(1*5)=157
157 % 10 = 7
So 137469-55-7 is a valid CAS Registry Number.

Synthesis of Selenoacetals from Enol Ethers

Braga, Antonio L.,Silveira, Claudio C.,Zeni, Gilson,Severo Filho, Wolmar A.,Stefani, Helio A.

, p. 206 - 207 (2007/10/03)

Diselenoacetals were obtained in good yields under mild conditions by treatment of benzeneselenol with enol ethers in the presence of boron trifluoride-diethyl ether; in the absence of Lewis Acid, monoseienoacetals were produced in good yields.

Synthesis of Monoselenoacetals Using Diisobutylaluminium Benzeneselenolate

Nishiyama, Yutaka,Nakata, Shinji,Hamanaka, Sawako

, p. 1775 - 1776 (2007/10/02)

Monoselenoacetals can be synthesized from the reaction of acetals with diisobutylaluminium benzeneselenolate (i-Bu2AlSePh) under mild conditions in good yields.Diselenoacetals are also obtained by traiting acetals with large excess amount of i-Bu2AlSePh.
