Check Digit Verification of cas no

The CAS Registry Mumber 1612763-93-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,1,2,7,6 and 3 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1612763-93:
(9*1)+(8*6)+(7*1)+(6*2)+(5*7)+(4*6)+(3*3)+(2*9)+(1*3)=165
165 % 10 = 5
So 1612763-93-5 is a valid CAS Registry Number.

Rapid assessment of protecting-group stability by using a robustness screen

Collins, Karl D.,Ruehling, Andreas,Lied, Fabian,Glorius, Frank

supporting information, p. 3800 - 3805 (2014/04/03)

An experimentally simple method has been developed to rapidly establish the stability of widely utilized silyl, acetal, and carbamate protecting groups to a given set of reaction conditions. Assessment of up to twelve protecting groups in a single experiment has been demonstrated. Evaluation of this protocol in two unrelated synthetic transformations suggests that this method can be used to select appropriate protecting groups in the design of synthetic routes.
