Check Digit Verification of cas no

The CAS Registry Mumber 127761-83-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,7,6 and 1 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 127761-83:
(8*1)+(7*2)+(6*7)+(5*7)+(4*6)+(3*1)+(2*8)+(1*3)=145
145 % 10 = 5
So 127761-83-5 is a valid CAS Registry Number.

Synthesis of a New Furanoid Glycal Auxiliary

Aly, Youssef L.,Pedersen, Erik B.

, p. 1641 - 1644 (2005)

A route is investigated for the synthesis of 3-O-allyl-1,4-anhydro-5-O- tert-butyldiphenylsilyl-2-deoxy-D-erythro-pent-1-enitol. The highest overall yield was obtained when 5′-O-(tert-butyldiphenylsilyl)thymidine was converted to the corresponding furanoi

One-pot synthesis of β-N-glycosyl imidazole analogues via a palladium-catalysed decarboxylative allylation

Xiang, Shaohua,He, Jingxi,Ma, Jimei,Liu, Xue-Wei

, p. 4222 - 4224 (2014/04/17)

A concise and highly efficient strategy for the synthesis of N-glycosyl imidazole analogues is reported. This reaction is based on a palladium catalysed decarboxylative allylation and three steps, namely, carbamation, decarboxylation and allylation are involved. All the substrates can afford the desired products with excellent yields and selectivities. the Partner Organisations 2014.
