Check Digit Verification of cas no

The CAS Registry Mumber 1314659-41-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,4,6,5 and 9 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1314659-41:
(9*1)+(8*3)+(7*1)+(6*4)+(5*6)+(4*5)+(3*9)+(2*4)+(1*1)=150
150 % 10 = 0
So 1314659-41-0 is a valid CAS Registry Number.

Unusual orthogonality in the cleavage process of closely related chelating protecting groups for carboxylic acids by using different metal ions

Mundinger, Stephan,Jakob, Uwe,Bannwarth, Willi

, p. 1258 - 1262 (2014)

Three structurally related relay protecting groups for carboxylic acids that are based on chelating amines have been developed. These protecting groups can easily be introduced by coupling the carboxylic acid and the corresponding amine in the presence of 2-(1Hbenzotriazole-1-yl)-1,1,3,3-tetramethyluronium tetrafluoroborate (TBTU). In addition to being stable to a whole array of reaction conditions, these protecting groups are also stable under acidic and basic conditions, allowing them to be used in combination with the ester protection of carboxylic acids. The cleavage of these protecting groups is activated by the chelation of metal ions, involving an unusual coordination of the amide nitrogen. Despite their similarity, cleavage of these protecting groups is possible in both a stepwise and an orthogonal fashion by applying different metal salts.
