Check Digit Verification of cas no

The CAS Registry Mumber 121995-11-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,9,9 and 5 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 121995-11:
(8*1)+(7*2)+(6*1)+(5*9)+(4*9)+(3*5)+(2*1)+(1*1)=127
127 % 10 = 7
So 121995-11-7 is a valid CAS Registry Number.

Transition-metal-free synthesis of pinacol alkylboronates from tosylhydrazones

Li, Huan,Wang, Long,Zhang, Yan,Wang, Jianbo

supporting information; experimental part, p. 2943 - 2946 (2012/04/18)

Highly efficient: Pinacol alkylboronates were synthesized by the reaction of tosylhydrazones with bis(pinacolato)diboron or pinacolborane under transition-metal-free conditions. This reaction represents an expeditious conversion of carbonyl functionality into a boronate group. Copyright
