77976-23-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 77976-23-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,9,7 and 6 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 77976-23:
(7*7)+(6*7)+(5*9)+(4*7)+(3*6)+(2*2)+(1*3)=189
189 % 10 = 9
So 77976-23-9 is a valid CAS Registry Number.

REACTIONS OF SULFOXONIUM ALLYLIDES WITH NITRILE OXIDES AND RING TRANSFORMATIONS OF THEIR REACTION PRODUCTS
Nakada,Y.,Hata,T.,Tamura,C.,Iwaoka,T.,Kondo,M.,Ide,J.
, p. 473 - 476 (2007/10/02)
Reactions of allylides (1) with nitrile oxides (2) afforded furanylglyoxylate oxime (3) and 6H-1,2-oxazine (4).Ring transformations of 3 and 4 gave 4 and pyrrolinone (6), respectively.
