Check Digit Verification of cas no
The CAS Registry Mumber 157458-84-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,4,5 and 8 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 157458-84:
(8*1)+(7*5)+(6*7)+(5*4)+(4*5)+(3*8)+(2*8)+(1*4)=169
169 % 10 = 9
So 157458-84-9 is a valid CAS Registry Number.

Difluoro(supermesityl)borane reacts with monolithiated hydrazines to give the corresponding fluoroborylated hydrazines 1a-c, which could not be dehydrofluorinated to yield definite products.From dilithiated hydrazine the 1,2-borylated species 2 was obtain
