Check Digit Verification of cas no

The CAS Registry Mumber 101884-75-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,1,8,8 and 4 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 101884-75:
(8*1)+(7*0)+(6*1)+(5*8)+(4*8)+(3*4)+(2*7)+(1*5)=117
117 % 10 = 7
So 101884-75-7 is a valid CAS Registry Number.

Non-directed copper-catalyzed regioselective C-H sulfonylation of phenothiazines

Liu, Caiyan,Shen, Yongli,Yuan, Kedong

, p. 5009 - 5013 (2019)

We develop a simple and general method for sulfonylation of phenothiazines under Cu(i) catalysis. The broad scope of aryl/alkyl sulfonyl chlorides was applicable to produce C3 sulfonylation products of phenothiazines in moderate to good yields. The further transformation of the sulfonylation products was successful, which afforded valuable polyheterocycles.
