Check Digit Verification of cas no

The CAS Registry Mumber 121572-28-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,5,7 and 2 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 121572-28:
(8*1)+(7*2)+(6*1)+(5*5)+(4*7)+(3*2)+(2*2)+(1*8)=99
99 % 10 = 9
So 121572-28-9 is a valid CAS Registry Number.

A method for the synthesis of alkynyl phenyl sulfides from alkynyltrimethylsilanes. A novel, efficient synthesis of the thienamycin intermediate from 3(R)-hydroxybutyric acid

Miyachi,Shibasaki

, p. 1975 - 1976 (2007/10/02)

The mechanism of the one-pot conversion of β-amino thiol esters of type 3 to β-lactams of type 4 has been clarified, and it is proposed that the actual active species is a PhSSPh-CuOTf complex. Through the use of this novel reaction, an efficient synthesis of the thienamycin intermediate 2, starting with 3(R)-hydroxybutyric acid, has been achieved. Furthermore, the combined reagents (PhSSPh-CuOTf) have been demonstrated to be a powerful source of PhS+ through the conversion of several alkynyltrimethylsilanes to alkynyl phenyl sulfides.
