Check Digit Verification of cas no

The CAS Registry Mumber 522607-81-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,2,2,6,0 and 7 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 522607-81:
(8*5)+(7*2)+(6*2)+(5*6)+(4*0)+(3*7)+(2*8)+(1*1)=134
134 % 10 = 4
So 522607-81-4 is a valid CAS Registry Number.

Mild, fast, and stereoselective epoxide opening by ketone enolate anions. Application to synthesis of the norlignan curculigine

Posner, Gary H.,Maxwell, John P.,Kahraman, Mehmet

, p. 3049 - 3054 (2007/10/03)

We report here that (1) enolate anions of five- to seven-membered cycloalkanones nucleophilically open cyclopentene and cyclohexene oxides in 57-76% yields and with 4-8:1 diastereoselectivity; (2) enolate anions formed regiospecifically via kinetic deprot
