Check Digit Verification of cas no

The CAS Registry Mumber 934271-05-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,3,4,2,7 and 1 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 934271-05:
(8*9)+(7*3)+(6*4)+(5*2)+(4*7)+(3*1)+(2*0)+(1*5)=163
163 % 10 = 3
So 934271-05-3 is a valid CAS Registry Number.

Studies on reactivity of azidoamides, intermediates in the synthesis of tetrahydroxypipecolic acid derivatives

Pino-Gonzalez, M.-Soledad,Assiego, Carmen,Ona, Noe

, p. 932 - 937 (2008/09/21)

Azido group reduction was observed by the treatment of a 2-azido-3-triisopropylsilyloxy heptonamide derivative with NaI in DMSO. The process allowed us to obtain a tetrahydroxypipecolic acid amide derivative. The same azido amide was treated with LiCl in DMSO, but desilylation occurred to give 3,6-anhydro-2-azido heptonamide.
