Calculate Digit Verification of CAS Registry Number 80667-94:
(7*8)+(6*0)+(5*6)+(4*6)+(3*7)+(2*9)+(1*4)=153
153 % 10 = 3
So 80667-94-3 is a valid CAS Registry Number.

Balgobin, Neil,Josephson, Staffan,Chattopadhyaya, Jyoti B.

, p. 3667 - 3670 (1981)

The PSEC group may be used to protect the hydroxyl function in conjunction with a variety of acid and base labile protecting groups; the PSEC group may be removed by treatment of triethylamine (15 equiv.) in dry pyridine solution within 20 h at 20 deg C while other base labile protecting groups remained intact.
