316827-99-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 316827-99-3 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 7 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 316827-99:
(8*3)+(7*1)+(6*6)+(5*8)+(4*2)+(3*7)+(2*9)+(1*9)=163
163 % 10 = 3
So 316827-99-3 is a valid CAS Registry Number.

Hetero-Diels-Alder synthesis of the spiroketal fragment of reveromycin A
El Sous,Rizzacasa
, p. 8591 - 8594 (2000)
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
