Check Digit Verification of cas no

The CAS Registry Mumber 149438-27-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,9,4,3 and 8 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 149438-27:
(8*1)+(7*4)+(6*9)+(5*4)+(4*3)+(3*8)+(2*2)+(1*7)=157
157 % 10 = 7
So 149438-27-7 is a valid CAS Registry Number.

Towards nitrile-substituted cyclopropanes-a slow-release protocol for safe and scalable applications of diazo acetonitrile

Hock, Katharina J.,Spitzner, Robin,Koenigs, Rene M.

supporting information, p. 2118 - 2122 (2017/07/24)

Diazo acetonitrile has long been neglected despite its high value in organic synthesis due to a high risk of explosions. Herein, we report our efforts towards the transient and safe generation of this diazo compound, its applications in iron catalyzed cyclopropanation and cyclopropenation reactions and the gram-scale synthesis of cyclopropyl nitriles.
