Check Digit Verification of cas no

The CAS Registry Mumber 101865-40-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,1,8,6 and 5 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 101865-40:
(8*1)+(7*0)+(6*1)+(5*8)+(4*6)+(3*5)+(2*4)+(1*0)=101
101 % 10 = 1
So 101865-40-1 is a valid CAS Registry Number.

Ring opening of N-hydroxyphthalimide to construct phenylurea derivatives

Wu, Yinhui,Lv, Bin,Zhang, Yanan,Gao, Pan,Zhang, Min,Yuan, Yu

, p. 2025 - 2033 (2021)

Arylurea and their analogues have been one of the most ubiquitous backbone during the past century, and extensive studies have been conducted to establish practical synthetic methods for their derivatives. In particular, it is an effective pathway to synthesize arylureas by using commercially available phthalimide compounds. Reported herein is a triethoxyphosphine promoted ring-opening of the N-hydroxyphthalimide (NHPI) by the nucleophilic attack of amines. This transformation shows a wide range of functional-group tolerance under mild reaction conditions.
