Check Digit Verification of cas no

The CAS Registry Mumber 1189516-75-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,9,5,1 and 6 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1189516-75:
(9*1)+(8*1)+(7*8)+(6*9)+(5*5)+(4*1)+(3*6)+(2*7)+(1*5)=193
193 % 10 = 3
So 1189516-75-3 is a valid CAS Registry Number.

An expedient synthesis of poly-substituted pyrroles from γ-ketonitriles via indium-mediated Barbier reaction strategy

Kim, Sung Hwan,Kim, Se Hee,Lee, Ka Young,Kim, Jae Nyoung

experimental part, p. 5744 - 5747 (2009/12/06)

We developed an efficient synthetic strategy of poly-substituted pyrroles via an indium-mediated Barbier type allylation from γ-ketonitriles. Initial attack of allylindium species occurred at the nitrile group selectively to form the enamine intermediate,
