120780-20-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 120780-20-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,7,8 and 0 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 120780-20:
(8*1)+(7*2)+(6*0)+(5*7)+(4*8)+(3*0)+(2*2)+(1*0)=93
93 % 10 = 3
So 120780-20-3 is a valid CAS Registry Number.

FUNCTIONALIZATION OF BENZOTHIAZINES VIA A SULFOXIMINE STABILIZED VINYL CARBANION
Harmata, Michael
, p. 5229 - 5232 (2007/10/02)
Benzothiazine 2b is readily deprotonated by n-BuLi to give the first example of a sulfoximine stabilized vinyl carbanion.The latter reacts efficiently with a variety of electrophiles.
