Check Digit Verification of cas no

The CAS Registry Mumber 74706-85-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,7,0 and 6 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 74706-85:
(7*7)+(6*4)+(5*7)+(4*0)+(3*6)+(2*8)+(1*5)=147
147 % 10 = 7
So 74706-85-7 is a valid CAS Registry Number.

New improvements in oligonucleotide synthesis by use of the p-nitrophenylethyl phosphate blocking group and its deprotection by DBU or DBN

Uhlmann, Eugen,Pfleiderer, Wolfgang

, p. 1181 - 1184 (2007/10/02)

Phosphate protection in the phosphotriester approach is improved by the new, versatile p-nitrophenylethyl group due to its stability in the condensation step and its clean removal by DBU and DBN respectively.
