316828-02-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 316828-02-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,1,6,8,2 and 8 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 316828-02:
(8*3)+(7*1)+(6*6)+(5*8)+(4*2)+(3*8)+(2*0)+(1*2)=141
141 % 10 = 1
So 316828-02-1 is a valid CAS Registry Number.

Hetero-Diels-Alder synthesis of the spiroketal fragment of reveromycin A
El Sous,Rizzacasa
, p. 8591 - 8594 (2007/10/03)
The asymmetric synthesis of the 6,6-spiroketal fragment 15 of the epidermal growth factor inhibitor reveromycin A (1) is described. A hetero-Diels-Alder reaction was utilized to construct the 6,6-spiroketal 14 and subsequent stereoselective hydroboration
