Check Digit Verification of cas no

The CAS Registry Mumber 189636-72-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,6,3 and 6 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 189636-72:
(8*1)+(7*8)+(6*9)+(5*6)+(4*3)+(3*6)+(2*7)+(1*2)=194
194 % 10 = 4
So 189636-72-4 is a valid CAS Registry Number.

Diphenyl methylphosphonate as a phosphonylation reagent with high diastereoselectivity at phosphorus

Moriarty, Robert M.,Tao, Anping,Condeiu, Cristian,Gilardi, Richard

, p. 2597 - 2600 (1997)

Reaction of diphenyl methylphosphonate with lithium alkoxides generated in situ from alcohols and butyllithium gives phenyl alkyl methylphosphonate diesters even with hindered alcohols and with high diastereoselectivity at phosphorus.
