1180643-01-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1180643-01-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,0,6,4 and 3 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1180643-01:
(9*1)+(8*1)+(7*8)+(6*0)+(5*6)+(4*4)+(3*3)+(2*0)+(1*1)=129
129 % 10 = 9
So 1180643-01-9 is a valid CAS Registry Number.

Ring-closing enyne metathesis (RCEYM) for the synthesis of cyclic sulfoximines
Füger, Bernhard,Bolm, Carsten
body text, p. 1601 - 1604 (2009/12/08)
Heterocyclic sulfoximines have been synthesized by RCEYM reactions starting from N-alkynyl-S-alkenyl sulfoximines in up to 79% yield. The products can be converted to tricyclic derivatives by a domino Diels-Alder/aromatization reaction sequence. Georg Thi
