Check Digit Verification of cas no

The CAS Registry Mumber 1233656-28-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,3,6,5 and 6 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1233656-28:
(9*1)+(8*2)+(7*3)+(6*3)+(5*6)+(4*5)+(3*6)+(2*2)+(1*8)=144
144 % 10 = 4
So 1233656-28-4 is a valid CAS Registry Number.

ROMP-derived oligomeric phosphates for application in facile benzylation

Long, Toby R.,Maity, Pradip K.,Samarakoon, Thiwanka B.,Hanson, Paul R.

supporting information; experimental part, p. 2904 - 2907 (2010/09/30)

The development of new ROMP-based oligomeric benzyl phosphates (OBP n) is reported for use as soluble, stable benzylating reagents. These oligomeric reagents are readily synthesized from commercially available materials and conveniently polymerized and purified in a one-pot process, affording bench-stable, pure white, free-flowing solids on multigram scale. Utilization in benzylation reactions with a variety of nucleophiles is reported.
