Check Digit Verification of cas no

The CAS Registry Mumber 907557-13-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,7,5,5 and 7 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 907557-13:
(8*9)+(7*0)+(6*7)+(5*5)+(4*5)+(3*7)+(2*1)+(1*3)=185
185 % 10 = 5
So 907557-13-5 is a valid CAS Registry Number.

Divergent synthesis of benzo[d]thiazoles by PIFA-mediated cyclization of β-oxo thioamides

Huang, Peng,Fu, Xiaolan,Liang, Yongjiu,Zhang, Rui,Dong, Dewen

experimental part, p. 121 - 128 (2012/07/14)

Efficient and divergent synthesis of benzo[d]thiazoles is developed from readily available b-oxo thioamides mediated by hypervalent iodine reagent phenyliodine bis(trifluoroaceate) (PIFA) based on reaction conditions selection, which involves the formation of a radical cation and its subsequent intramolecular cyclization process.
