91861-30-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 91861-30-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,8,6 and 1 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 91861-30:
(7*9)+(6*1)+(5*8)+(4*6)+(3*1)+(2*3)+(1*0)=142
142 % 10 = 2
So 91861-30-2 is a valid CAS Registry Number.

Stereoselective Synthesis of (+/-)-Trichodiene

Harding, Kenn E.,Clement, K. S.,Tseng, C.-Y.

, p. 4403 - 4410 (2007/10/02)

Details of a convergent stereoselective synthesis of trichodiene (1) from simple monocyclic starting materials are reported.Stereochemical control is effected by Nazarov cyclization of dienone 14 and C-C bond cleavage of the resulting tricyclic products 1

A Highly Stereoselective, Convergent Synthesis of (+/-)-Trichodiene

Harding, Kenn E.,Clement, Katherine S.

, p. 3870 - 3871 (2007/10/02)

A short, highly stereoselective synthesis of (+/-)-trichodiene had been completed via a convergent strategy using a Nazarov cyclization for stereospecific formation of the adjacent quarternary centers.
