Check Digit Verification of cas no
The CAS Registry Mumber 1948-40-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,9,4 and 8 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1948-40:
(6*1)+(5*9)+(4*4)+(3*8)+(2*4)+(1*0)=99
99 % 10 = 9
So 1948-40-9 is a valid CAS Registry Number.

NCBSI/KI: A Reagent System for Iodination of Aromatics through in Situ Generation of I-Cl
Palav, Amey,Misal, Balu,Chaturbhuj, Ganesh
, p. 12467 - 12474 (2021/08/24)
In situ iodine monochloride (I-Cl) generation followed by iodination of aromatics using NCBSI/KI system has been developed. The NCBSI reagent requires no activation due to longer bond length, lower bond dissociation energy, and higher absolute charge density on nitrogen. The system is adequate for mono- and diiodination of a wide range of moderate to highly activated arenes with good yield and purity. Moreover, the precursor N-(benzenesulfonyl)benzenesulfonamide can be recovered and transformed to NCBSI, making the protocol eco-friendly and cost-effective.
Efficient and sustainable laccase-catalyzed iodination of: P -substituted phenols using KI as iodine source and aerial O2 as oxidant
