Check Digit Verification of cas no

The CAS Registry Mumber 131968-57-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,9,6 and 8 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 131968-57:
(8*1)+(7*3)+(6*1)+(5*9)+(4*6)+(3*8)+(2*5)+(1*7)=145
145 % 10 = 5
So 131968-57-5 is a valid CAS Registry Number.

Hydroboration of C-arylglucals. Synthesis of the β-C-arylglucoside nucleus of chaetiacandin

Friesen,Daljeet

, p. 6133 - 6136 (2007/10/02)

The hydroborations of the C-arylglucals 3a-c obtained from palladium catalyzed coupling reactions, provide the corresponding β-C-arylglucosides. Depending upon the conditions chosen for the oxidative workup, either the alcohols 5a-c or the products resulting from silyl migration (4a-c) are readily obtained. The palladium catalyzed coupling-hydroboration sequence has been applied to the synthesis of the β-C-arylglucoside nucleus of chaetiacandin, an anti-yeast antibiotic of the papulacandin family.
