1202278-81-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1202278-81-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,2,2,7 and 8 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1202278-81:
(9*1)+(8*2)+(7*0)+(6*2)+(5*2)+(4*7)+(3*8)+(2*8)+(1*1)=116
116 % 10 = 6
So 1202278-81-6 is a valid CAS Registry Number.

Synthesis and characterisation of severely hindered P-OR compounds
Williams, D. Bradley G.,Netshiozwi, Takelani E.
experimental part, p. 9973 - 9982 (2010/02/27)
P-Cl substrates were converted into their P-OR analogues from hindered alcohols using an amine base. Where the system was severely hindered, more forcing conditions were required that necessitated the presence of a metal alkoxide nucleophile before succes
