1202865-75-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1202865-75-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,2,8,6 and 5 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1202865-75:
(9*1)+(8*2)+(7*0)+(6*2)+(5*8)+(4*6)+(3*5)+(2*7)+(1*5)=135
135 % 10 = 5
So 1202865-75-5 is a valid CAS Registry Number.

Stereoselective synthesis of 2,3,4-trisubstituted tetrahydrothiophenes
Besada, Pedro,Pérez, Manuel,Gómez, Generosa,Fall, Yagamare
scheme or table, p. 6941 - 6943 (2010/02/27)
We describe an efficient new approach for the synthesis of highly substituted chiral tetrahydrothiophenes, based on the oxidation of a chiral furan substrate with singlet oxygen, followed by intramolecular hetero Michael addition.
