916991-69-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 916991-69-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,6,9,9 and 1 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 916991-69:
(8*9)+(7*1)+(6*6)+(5*9)+(4*9)+(3*1)+(2*6)+(1*9)=220
220 % 10 = 0
So 916991-69-0 is a valid CAS Registry Number.

Synthetic studies toward bryostatin 1: preparation of a C1-C16 fragment by pyran annulation
Keck, Gary E.,Welch, Dennie S.,Poudel, Yam B.
, p. 8267 - 8270 (2007/10/03)
An expeditious assembly of a C1-C16 subunit of bryostatin 1 is described. A pyran annulation reaction was utilized to form the B-ring by reaction of a hydroxy-allylsilane with a fully elaborated A-ring subunit. This annulation proces
