141987-84-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 141987-84-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,1,9,8 and 7 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 141987-84:
(8*1)+(7*4)+(6*1)+(5*9)+(4*8)+(3*7)+(2*8)+(1*4)=160
160 % 10 = 0
So 141987-84-0 is a valid CAS Registry Number.

TOTAL SYNTHESIS OF (+)-ERYSOTRINE VIA ASYMMETRIC DIELS-ALDER REACTION UNDER SUPER HIGH PRESSURE
Tsuda, Yoshisuke,Hosoi, Shinzo,Katagiri, Nobuya,Kaneko, Chikara,Sano, Takehiro
, p. 497 - 502 (1992)
The first total synthesis of (+)-erysotrine in a chiral form was achieved through application of Diels-Alder reaction of a chiral dioxopyrroline with 1-methoxy-3-trimethylsilyloxybutadiene under a 10 Kbar pressure.
