Check Digit Verification of cas no

The CAS Registry Mumber 1374568-26-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,4,5,6 and 8 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1374568-26:
(9*1)+(8*3)+(7*7)+(6*4)+(5*5)+(4*6)+(3*8)+(2*2)+(1*6)=189
189 % 10 = 9
So 1374568-26-9 is a valid CAS Registry Number.

Metal-Free, Oxidant-Free, and Controllable Graphene Oxide Catalyzed Direct Iodination of Arenes and Ketones

Zhang, Jingyu,Li, Shiguang,Deng, Guo-Jun,Gong, Hang

, p. 376 - 380 (2018)

A direct, metal-free, and oxidant-free method for the graphene oxide (GO)-catalyzed iodination of arenes and ketones with iodine in a neutral medium was explored. This iodination protocol was performed by using a simple technique to avoid the use of external metal catalysts and oxidants and harsh acidic/basic reaction conditions. In addition, by this method the degree of iodination could be controlled, and the reaction was scalable and compatible with air. This strategy opens a new field for GO-catalyzed chemistry and provides an avenue for the convenient direct iodination of arenes and ketones.
