919770-72-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 919770-72-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,9,7,7 and 0 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 919770-72:
(8*9)+(7*1)+(6*9)+(5*7)+(4*7)+(3*0)+(2*7)+(1*2)=212
212 % 10 = 2
So 919770-72-2 is a valid CAS Registry Number.

Ji, Nan,O'Dowd, Hardwin,Rosen, Brad M.,Myers, Andrew G.
, p. 14825 - 14827 (2008/02/09)
An enantioselective synthetic route to the enediyne antibiotic N1999A2 (1) is described, proceeding in 21 steps (0.4% yield, 77% average yield per step) from (R)-(+)-glycidol. The route involves the convergent assembly of three components: a (1-iodovinyl)
