Check Digit Verification of cas no

The CAS Registry Mumber 198754-79-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,8,7,5 and 4 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 198754-79:
(8*1)+(7*9)+(6*8)+(5*7)+(4*5)+(3*4)+(2*7)+(1*9)=209
209 % 10 = 9
So 198754-79-9 is a valid CAS Registry Number.

Enantioselective acyclic stereoselection under catalyst control - III. A very short asymmetric synthesis of the bryostatin C1-C9 segment using the chiral oxazaborolidinone-promoted aldol reaction

Kiyooka, Syun-Ichi,Maeda, Hirofumi

, p. 3371 - 3374 (2007/10/03)

A very short asymmetric synthesis of the bryostatin C1-C9 segment was achieved by three sequential chiral oxazaborolidinone-promoted aldol reactions under 'catalyst control'. This synthetic methodology is based on a direct asymmetric
