Check Digit Verification of cas no

The CAS Registry Mumber 1280536-79-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,0,5,3 and 6 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1280536-79:
(9*1)+(8*2)+(7*8)+(6*0)+(5*5)+(4*3)+(3*6)+(2*7)+(1*9)=159
159 % 10 = 9
So 1280536-79-9 is a valid CAS Registry Number.

An efficient photoinduced deprotection of aromatic acetals and ketals

Thevenet, Damien,Neier, Reinhard

, p. 331 - 346 (2011)

A novel type of photodeprotection reaction of simple aromatic acetals and ketals is described. The deprotection is highly efficient under optimized conditions. The aromatic ring confers the photoreactivity to the compounds. The efficiency of the process depends on the structure of the acetal moiety. The common minor side reaction, the photooxidation, becomes the major reaction pathway in the cases of cyclic acetals. The use of photon as only reagent makes this procedure especially attractive for acetal deprotection.
