Check Digit Verification of cas no

The CAS Registry Mumber 1231672-31-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,1,6,7 and 2 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1231672-31:
(9*1)+(8*2)+(7*3)+(6*1)+(5*6)+(4*7)+(3*2)+(2*3)+(1*1)=123
123 % 10 = 3
So 1231672-31-3 is a valid CAS Registry Number.

Orthogonally protected glycerols and 2-aminodiols: Useful building blocks in heterocyclic chemistry

Ollivier, Anthony,Goubert, Marlene,Tursun, Ahmatjan,Canet, Isabelle,Sinibaldia, Marie-Eve

experimental part, p. 108 - 126 (2010/10/03)

The efficient synthesis of orthogonally protected glycerols, 2-aminopropane-1,3-diols and 2-aminobutane-1,4-diols that can constitute useful tools in heterocyclic chemistry, is reported. These interesting tri-functionalized small synthons were easily prepared from serine or aspartic acid. In addition, these substrates can be readily transformed into their iodide derivatives in very good yields. ARKAT USA, Inc.
