Check Digit Verification of cas no

The CAS Registry Mumber 1202381-72-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,2,3,8 and 1 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1202381-72:
(9*1)+(8*2)+(7*0)+(6*2)+(5*3)+(4*8)+(3*1)+(2*7)+(1*2)=103
103 % 10 = 3
So 1202381-72-3 is a valid CAS Registry Number.

Diastereoselective synthesis of syn-1,3-diols by titanium-mediated reductive coupling of propargylic alcohols

Tian, Guo-Qiang,Kaiser, Thomas,Yang, Jiong

supporting information; experimental part, p. 288 - 290 (2010/03/25)

(Figure presented) A titanium-mediated, hydroxy-directed reductive coupling reaction of propargylic alcohols and aldehydes/ketones Is described. Excellent diastereoselectivity and synthetically useful yields have been obtained for a range of substrates. This transformation has enabled a highly convergent three-component approach to syn-1,3-diols using (trimethylsilyl)acetylene as a C1 linchpin.
