Check Digit Verification of cas no

The CAS Registry Mumber 1228675-52-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,8,6,7 and 5 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1228675-52:
(9*1)+(8*2)+(7*2)+(6*8)+(5*6)+(4*7)+(3*5)+(2*5)+(1*2)=172
172 % 10 = 2
So 1228675-52-2 is a valid CAS Registry Number.

Polyketide assembly by alkene-alkyne reductive cross-coupling: Spiroketals through the union of homoallylic alcohols

Canterbury, Daniel P.,Micalizio, Glenn C.

, p. 7602 - 7604 (2010)

A reaction sequence composed of regioselective formal hydroalkynylation, reductive ene-yne cross-coupling, and oxidative cyclization has been developed to prepare stereochemically dense spiroketals. Overall, the chemistry defines a three-component coupling process for the union of two homoallylic alcohol-based substrates with trimethylsilylacetylene.
