2764-91-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 2764-91-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,7,6 and 4 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 2764-91:
(6*2)+(5*7)+(4*6)+(3*4)+(2*9)+(1*1)=102
102 % 10 = 2
So 2764-91-2 is a valid CAS Registry Number.

Application of benzyl protecting groups in the synthesis of prenylated aromatic compounds
Odejinmi, Sina I.,Wiemer, David F.
, p. 3871 - 3874 (2007/10/03)
Benzyl ethers have proven to be useful protecting groups for synthesis of phenols bearing isoprenoid chains because the benzyl groups can tolerate the conditions of halogen-metal exchange used to introduce the side chains yet are cleaved in good yields upon treatment with sodium s-butanol.
