Check Digit Verification of cas no

The CAS Registry Mumber 1431660-67-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,3,1,6,6 and 0 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1431660-67:
(9*1)+(8*4)+(7*3)+(6*1)+(5*6)+(4*6)+(3*0)+(2*6)+(1*7)=141
141 % 10 = 1
So 1431660-67-1 is a valid CAS Registry Number.

A variation of the Fischer indolization involving condensation of quinone monoketals and aliphatic hydrazines

Zhang, Jinzhu,Yin, Zhiwei,Leonard, Patrick,Wu, Jing,Sioson, Kate,Liu, Che,Lapo, Robert,Zheng, Shengping

, p. 1753 - 1757,5 (2013/04/10)

A new twist: A one-pot nitrous acid free, diazonium-free, and transition-metal-free variation of the Fischer indole synthesis has been developed. Condensation of quinone monoketals and aliphatic hydrazine hydrochlorides afforded indoles via intermediate alkylaryldiazenes. This method will complement the classical Fischer indole synthesis by providing indoles in two steps from widely available phenols under mild conditions. Copyright
