Check Digit Verification of cas no

The CAS Registry Mumber 1215311-32-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,5,3,1 and 1 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1215311-32:
(9*1)+(8*2)+(7*1)+(6*5)+(5*3)+(4*1)+(3*1)+(2*3)+(1*2)=92
92 % 10 = 2
So 1215311-32-2 is a valid CAS Registry Number.

Lactose as an inexpensive starting material for the preparation of aldohexos-5-uloses: synthesis of l-ribo and d-lyxo derivatives

Guazzelli, Lorenzo,Catelani, Giorgio,D'Andrea, Felicia

experimental part, p. 369 - 376 (2010/04/02)

Partially protected derivatives of l-ribo- and d-lyxo-aldohexos-5-ulose have been prepared starting from triacetonlactose dimethyl acetal derivatives. Key steps of the synthetic sequences are (a) the synthesis of 4′-deoxy-4′-eno- and 6′-deoxy-5′-eno lactose derivatives, and (b) the epoxidation-methanolysis of the above-mentioned enol ethers to give 1,5-bis-glycopyranosides, masked form of the target 1,5-dicarbonyl hexoses.
