Check Digit Verification of cas no

The CAS Registry Mumber 1427729-71-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,7,7,2 and 9 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1427729-71:
(9*1)+(8*4)+(7*2)+(6*7)+(5*7)+(4*2)+(3*9)+(2*7)+(1*1)=182
182 % 10 = 2
So 1427729-71-2 is a valid CAS Registry Number.

A Sequential Pd-AAA/Cross-Metathesis/Cope Rearrangement Strategy for the Stereoselective Synthesis of Chiral Butenolides

Aubert, Sidonie,Katsina, Tania,Arseniyadis, Stellios

supporting information, p. 2231 - 2235 (2019/03/29)

A practical and highly enantio- (up to 94:6 er) and diastereoselective (up to >20:1 dr) synthesis of I-butenolides bearing two adjacent stereogenic centers is reported featuring a sequential direct palladium-catalyzed asymmetric allylic alkylation/(E)-selective cross-metathesis/[3,3]-sigmatropic Cope rearrangement from readily available α-substituted (5H)-furan-2-ones.
