Check Digit Verification of cas no

The CAS Registry Mumber 202476-38-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,2,4,7 and 6 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 202476-38:
(8*2)+(7*0)+(6*2)+(5*4)+(4*7)+(3*6)+(2*3)+(1*8)=108
108 % 10 = 8
So 202476-38-8 is a valid CAS Registry Number.

Enantioselective synthesis of threo-α,β-dihydroxyphosphonates by asymmetric dihydroxylation of 1(E)-alkenylphosphonates with AD-mix reagents

Yokomatsu, Tsutomu,Yamagishi, Takehiro,Suemune, Kenji,Yoshida, Yoshinori,Shibuya, Shiroshi

, p. 767 - 780 (1998)

Asymmetric dihydroxylation (AD) of 1(E)-alkenylphosphonates with an AD- mix-α or -β reagent was examined to give a series of optically active threo-α,β-dihydroxyphosphonates. Good enantioselectivity (>88% ee) was observed in the AD reaction of 1(E)-alkenylphosphonates with conjugated aromatic substituents. The steric effects of the ester functionality in the course of the dihydroxylation were also evaluated. Enantioselectivity and yield were significantly improved when the AD reaction was carded out with dimethyl phosphonate instead of diethyl phosphonate.
