Check Digit Verification of cas no

The CAS Registry Mumber 1448709-50-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,8,7,0 and 9 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1448709-50:
(9*1)+(8*4)+(7*4)+(6*8)+(5*7)+(4*0)+(3*9)+(2*5)+(1*0)=189
189 % 10 = 9
So 1448709-50-9 is a valid CAS Registry Number.

Iodine-catalyzed regioselective sulfenylation of indoles with sulfonyl hydrazides

Yang, Fu-Lai,Tian, Shi-Kai

supporting information, p. 4929 - 4932 (2013/06/04)

New S in town: Sulfonyl hydrazides smoothly undergo sulfenylation with indoles in the presence of 10 mol % I2 to give structurally diverse indole thioethers in moderate to excellent yields with extremely high regioselectivity. This study paves the way for the use of sulfonyl hydrazides as unique sulfur electrophiles in chemical synthesis. Copyright
